+All items below are to be completed by the owner of the given release.
+
+- [ ] Create release branch with major and minor only ( e.g. release/v0.X ) if it doesn't exist.
+- [ ] Assign release candidate tag to the release branch HEAD (e.g. `v0.X.0-beta-rc.0`, `v0.X.0-beta-rc.1`, ... `v0.X.0-beta-rc.N`).
+- [ ] Generate and edit release notes in CHANGELOG.md.
+
+- [ ] **Waku test and fleets validation**
+  - [ ] Ensure all the unit tests (specifically js-waku tests) are green against the release candidate.
+  - [ ] Deploy the release candidate to `waku.test` only through [deploy-waku-test job](https://ci.infra.status.im/job/nim-waku/job/deploy-waku-test/) and wait for it to finish (Jenkins access required; ask the infra team if you don't have it).
+    - After completion, disable [deployment job](https://ci.infra.status.im/job/nim-waku/) so that its version is not updated on every merge to master.
+    - Verify the deployed version at https://fleets.waku.org/.
+    - Confirm the container image exists on [Harbor](https://harbor.status.im/harbor/projects/9/repositories/nwaku/artifacts-tab).
+  - [ ] Analyze Kibana logs from the previous month (since the last release was deployed) for possible crashes or errors in `waku.test`.
+      - Most relevant logs are `(fleet: "waku.test" AND message: "SIGSEGV")`.
+  - [ ] Enable again the `waku.test` fleet to resume auto-deployment of the latest `master` commit.
+
+- [ ] **Proceed with release**
+
+  - [ ] Assign a final release tag (`v0.X.0-beta`) to the same commit that contains the validated release-candidate tag (e.g. `v0.X.0-beta-rc.N`) and submit a PR from the release branch to `master`.
+  - [ ] Update [nwaku-compose](https://github.com/logos-messaging/nwaku-compose) and [waku-simulator](https://github.com/logos-messaging/waku-simulator) according to the new release.
+  - [ ] Bump nwaku dependency in [waku-rust-bindings](https://github.com/logos-messaging/waku-rust-bindings) and make sure all examples and tests work.
+  - [ ] Bump nwaku dependency in [waku-go-bindings](https://github.com/logos-messaging/waku-go-bindings) and make sure all tests work.
+  - [ ] Create GitHub release (https://github.com/logos-messaging/nwaku/releases).
+  - [ ] Submit a PR to merge the release branch back to `master`. Make sure you use the option "Merge pull request (Create a merge commit)" to perform the merge. Ping repo admin if this option is not available.
+
+- [ ] **Promote release to fleets**
+  - [ ] Ask the PM lead to announce the release.
+  - [ ] Update infra config with any deprecated arguments or changed options.
+  - [ ] Update waku.sandbox with [this deployment job](https://ci.infra.status.im/job/nim-waku/job/deploy-waku-sandbox/).

+# AGENTS.md - AI Coding Context
+
+This file provides essential context for LLMs assisting with Logos Messaging development.
+
+## Project Identity
+
+Logos Messaging is designed as a shared public network for generalized messaging, not application-specific infrastructure.
+
+This project is a Nim implementation of a libp2p protocol suite for private, censorship-resistant P2P messaging. It targets resource-restricted devices and privacy-preserving communication.
+
+Logos Messaging was formerly known as Waku. Waku-related terminology remains within the codebase for historical reasons.
+
+### Design Philosophy
+
+Key architectural decisions:
+
+Resource-restricted first: Protocols differentiate between full nodes (relay) and light clients (filter, lightpush, store). Light clients can participate without maintaining full message history or relay capabilities. This explains the client/server split in protocol implementations.
+
+Privacy through unlinkability: RLN (Rate Limiting Nullifier) provides DoS protection while preserving sender anonymity. Messages are routed through pubsub topics with automatic sharding across 8 shards. Code prioritizes metadata privacy alongside content encryption.
+
+Scalability via sharding: The network uses automatic content-topic-based sharding to distribute traffic. This is why you'll see sharding logic throughout the codebase and why pubsub topic selection is protocol-level, not application-level.
+
+See [documentation](https://docs.waku.org/learn/) for architectural details.
+
+### Core Protocols
+- Relay: Pub/sub message routing using GossipSub
+- Store: Historical message retrieval and persistence
+- Filter: Lightweight message filtering for resource-restricted clients
+- Lightpush: Lightweight message publishing for clients
+- Peer Exchange: Peer discovery mechanism
+- RLN Relay: Rate limiting nullifier for spam protection
+- Metadata: Cluster and shard metadata exchange between peers
+- Mix: Mixnet protocol for enhanced privacy through onion routing
+- Rendezvous: Alternative peer discovery mechanism
+
+### Key Terminology
+- ENR (Ethereum Node Record): Node identity and capability advertisement
+- Multiaddr: libp2p addressing format (e.g., `/ip4/127.0.0.1/tcp/60000/p2p/16Uiu2...`)
+- PubsubTopic: Gossipsub topic for message routing (e.g., `/waku/2/default-waku/proto`)
+- ContentTopic: Application-level message categorization (e.g., `/my-app/1/chat/proto`)
+- Sharding: Partitioning network traffic across topics (static or auto-sharding)
+- RLN (Rate Limiting Nullifier): Zero-knowledge proof system for spam prevention
+
+### Specifications
+All specs are at [rfc.vac.dev/waku](https://rfc.vac.dev/waku). RFCs use `WAKU2-XXX` format (not legacy `WAKU-XXX`).
+
+## Architecture
+
+### Protocol Module Pattern
+Each protocol typically follows this structure:
+```
+waku_<protocol>/
+├── protocol.nim       # Main protocol type and handler logic
+├── client.nim         # Client-side API
+├── rpc.nim           # RPC message types
+├── rpc_codec.nim     # Protobuf encoding/decoding
+├── common.nim        # Shared types and constants
+└── protocol_metrics.nim  # Prometheus metrics
+```
+
+### WakuNode Architecture
+- WakuNode (`waku/node/waku_node.nim`) is the central orchestrator
+- Protocols are "mounted" onto the node's switch (libp2p component)
+- PeerManager handles peer selection and connection management
+- Switch provides libp2p transport, security, and multiplexing
+
+Example protocol type definition:
+```nim
+type WakuFilter* = ref object of LPProtocol
+  subscriptions*: FilterSubscriptions
+  peerManager: PeerManager
+  messageCache: TimedCache[string]
+```
+
+## Development Essentials
+
+### Build Requirements
+- Nim 2.x (check `waku.nimble` for minimum version)
+- Rust toolchain (required for RLN dependencies)
+- Build system: Make with nimbus-build-system
+
+### Build System
+The project uses Makefile with nimbus-build-system (Status's Nim build framework):
+```bash
+# Initial build (updates submodules)
+make wakunode2
+
+# After git pull, update submodules
+make update
+
+# Build with custom flags
+make wakunode2 NIMFLAGS="-d:chronicles_log_level=DEBUG"
+```
+
+Note: The build system uses `--mm:refc` memory management (automatically enforced). Only relevant if compiling outside the standard build system.
+
+### Common Make Targets
+```bash
+make wakunode2          # Build main node binary
+make test               # Run all tests
+make testcommon         # Run common tests only
+make libwakuStatic      # Build static C library
+make chat2              # Build chat example
+make install-nph        # Install git hook for auto-formatting
+```
+
+### Testing
+```bash
+# Run all tests
+make test
+
+# Run specific test file
+make test tests/test_waku_enr.nim
+
+# Run specific test case from file
+make test tests/test_waku_enr.nim "check capabilities support"
+
+# Build and run test separately (for development iteration)
+make test tests/test_waku_enr.nim
+```
+
+Test structure uses `testutils/unittests`:
+```nim
+import testutils/unittests
+
+suite "Waku ENR - Capabilities":
+  test "check capabilities support":
+    ## Given
+    let bitfield: CapabilitiesBitfield = 0b0000_1101u8
+    
+    ## Then
+    check:
+      bitfield.supportsCapability(Capabilities.Relay)
+      not bitfield.supportsCapability(Capabilities.Store)
+```
+
+### Code Formatting
+Mandatory: All code must be formatted with `nph` (vendored in `vendor/nph`)
+```bash
+# Format specific file
+make nph/waku/waku_core.nim
+
+# Install git pre-commit hook (auto-formats on commit)
+make install-nph
+```
+The nph formatter handles all formatting details automatically, especially with the pre-commit hook installed. Focus on semantic correctness.
+
+### Logging
+Uses `chronicles` library with compile-time configuration:
+```nim
+import chronicles
+
+logScope:
+  topics = "waku lightpush"
+
+info "handling request", peerId = peerId, topic = pubsubTopic
+error "request failed", error = msg
+```
+
+Compile with log level:
+```bash
+nim c -d:chronicles_log_level=TRACE myfile.nim
+```
+
+
+## Code Conventions
+
+Common pitfalls:
+- Always handle Result types explicitly
+- Avoid global mutable state: Pass state through parameters
+- Keep functions focused: Under 50 lines when possible
+- Prefer compile-time checks (`static assert`) over runtime checks
+
+### Naming
+- Files/Directories: `snake_case` (e.g., `waku_lightpush`, `peer_manager`)
+- Procedures: `camelCase` (e.g., `handleRequest`, `pushMessage`)
+- Types: `PascalCase` (e.g., `WakuFilter`, `PubsubTopic`)
+- Constants: `PascalCase` (e.g., `MaxContentTopicsPerRequest`)
+- Constructors: `func init(T: type Xxx, params): T`
+- For ref types: `func new(T: type Xxx, params): ref T`
+- Exceptions: `XxxError` for CatchableError, `XxxDefect` for Defect
+- ref object types: `XxxRef` suffix
+
+### Imports Organization
+Group imports: stdlib, external libs, internal modules:
+```nim
+import
+  std/[options, sequtils],      # stdlib
+  results, chronicles, chronos,  # external
+  libp2p/peerid
+import
+  ../node/peer_manager,          # internal (separate import block)
+  ../waku_core,
+  ./common
+```
+
+### Async Programming
+Uses chronos, not stdlib `asyncdispatch`:
+```nim
+proc handleRequest(
+    wl: WakuLightPush, peerId: PeerId
+): Future[WakuLightPushResult] {.async.} =
+  let res = await wl.pushHandler(peerId, pubsubTopic, message)
+  return res
+```
+
+### Error Handling
+The project uses both Result types and exceptions:
+
+Result types from nim-results are used for protocol and API-level errors:
+```nim
+proc subscribe(
+    wf: WakuFilter, peerId: PeerID
+): Future[FilterSubscribeResult] {.async.} =
+  if contentTopics.len > MaxContentTopicsPerRequest:
+    return err(FilterSubscribeError.badRequest("exceeds maximum"))
+  
+  # Handle Result with isOkOr
+  (await wf.subscriptions.addSubscription(peerId, criteria)).isOkOr:
+    return err(FilterSubscribeError.serviceUnavailable(error))
+  
+  ok()
+```
+
+Exceptions still used for:
+- chronos async failures (CancelledError, etc.)
+- Database/system errors
+- Library interop
+
+Most files start with `{.push raises: [].}` to disable exception tracking, then use try/catch blocks where needed.
+
+### Pragma Usage
+```nim
+{.push raises: [].}  # Disable default exception tracking (at file top)
+
+proc myProc(): Result[T, E] {.async.} =  # Async proc
+```
+
+### Protocol Inheritance
+Protocols inherit from libp2p's `LPProtocol`:
+```nim
+type WakuLightPush* = ref object of LPProtocol
+  rng*: ref rand.HmacDrbgContext
+  peerManager*: PeerManager
+  pushHandler*: PushMessageHandler
+```
+
+### Type Visibility
+- Public exports use `*` suffix: `type WakuFilter* = ...`
+- Fields without `*` are module-private
+
+## Style Guide Essentials
+
+This section summarizes key Nim style guidelines relevant to this project. Full guide: https://status-im.github.io/nim-style-guide/
+
+### Language Features
+
+Import and Export
+- Use explicit import paths with std/ prefix for stdlib
+- Group imports: stdlib, external, internal (separate blocks)
+- Export modules whose types appear in public API
+- Avoid include
+
+Macros and Templates
+- Avoid macros and templates - prefer simple constructs
+- Avoid generating public API with macros
+- Put logic in templates, use macros only for glue code
+
+Object Construction
+- Prefer Type(field: value) syntax
+- Use Type.init(params) convention for constructors
+- Default zero-initialization should be valid state
+- Avoid using result variable for construction
+
+ref object Types
+- Avoid ref object unless needed for:
+  - Resource handles requiring reference semantics
+  - Shared ownership
+  - Reference-based data structures (trees, lists)
+  - Stable pointer for FFI
+- Use explicit ref MyType where possible
+- Name ref object types with Ref suffix: XxxRef
+
+Memory Management
+- Prefer stack-based and statically sized types in core code
+- Use heap allocation in glue layers
+- Avoid alloca
+- For FFI: use create/dealloc or createShared/deallocShared
+
+Variable Usage
+- Use most restrictive of const, let, var (prefer const over let over var)
+- Prefer expressions for initialization over var then assignment
+- Avoid result variable - use explicit return or expression-based returns
+
+Functions
+- Prefer func over proc
+- Avoid public (*) symbols not part of intended API
+- Prefer openArray over seq for function parameters
+
+Methods (runtime polymorphism)
+- Avoid method keyword for dynamic dispatch
+- Prefer manual vtable with proc closures for polymorphism
+- Methods lack support for generics
+
+Miscellaneous
+- Annotate callback proc types with {.raises: [], gcsafe.}
+- Avoid explicit {.inline.} pragma
+- Avoid converters
+- Avoid finalizers
+
+Type Guidelines
+
+Binary Data
+- Use byte for binary data
+- Use seq[byte] for dynamic arrays
+- Convert string to seq[byte] early if stdlib returns binary as string
+
+Integers
+- Prefer signed (int, int64) for counting, lengths, indexing
+- Use unsigned with explicit size (uint8, uint64) for binary data, bit ops
+- Avoid Natural
+- Check ranges before converting to int
+- Avoid casting pointers to int
+- Avoid range types
+
+Strings
+- Use string for text
+- Use seq[byte] for binary data instead of string
+
+### Error Handling
+
+Philosophy
+- Prefer Result, Opt for explicit error handling
+- Use Exceptions only for legacy code compatibility
+
+Result Types
+- Use Result[T, E] for operations that can fail
+- Use cstring for simple error messages: Result[T, cstring]
+- Use enum for errors needing differentiation: Result[T, SomeErrorEnum]
+- Use Opt[T] for simple optional values
+- Annotate all modules: {.push raises: [].} at top
+
+Exceptions (when unavoidable)
+- Inherit from CatchableError, name XxxError
+- Use Defect for panics/logic errors, name XxxDefect
+- Annotate functions explicitly: {.raises: [SpecificError].}
+- Catch specific error types, avoid catching CatchableError
+- Use expression-based try blocks
+- Isolate legacy exception code with try/except, convert to Result
+
+Common Defect Sources
+- Overflow in signed arithmetic
+- Array/seq indexing with []
+- Implicit range type conversions
+
+Status Codes
+- Avoid status code pattern
+- Use Result instead
+
+### Library Usage
+
+Standard Library
+- Use judiciously, prefer focused packages
+- Prefer these replacements:
+  - async: chronos
+  - bitops: stew/bitops2
+  - endians: stew/endians2
+  - exceptions: results
+  - io: stew/io2
+
+Results Library
+- Use cstring errors for diagnostics without differentiation
+- Use enum errors when caller needs to act on specific errors
+- Use complex types when additional error context needed
+- Use isOkOr pattern for chaining
+
+Wrappers (C/FFI)
+- Prefer native Nim when available
+- For C libraries: use {.compile.} to build from source
+- Create xxx_abi.nim for raw ABI wrapper
+- Avoid C++ libraries
+
+Miscellaneous
+- Print hex output in lowercase, accept both cases
+
+### Common Pitfalls
+
+- Defects lack tracking by {.raises.}
+- nil ref causes runtime crashes
+- result variable disables branch checking
+- Exception hierarchy unclear between Nim versions
+- Range types have compiler bugs
+- Finalizers infect all instances of type
+
+## Common Workflows
+
+### Adding a New Protocol
+1. Create directory: `waku/waku_myprotocol/`
+2. Define core files:
+   - `rpc.nim` - Message types
+   - `rpc_codec.nim` - Protobuf encoding
+   - `protocol.nim` - Protocol handler
+   - `client.nim` - Client API
+   - `common.nim` - Shared types
+3. Define protocol type in `protocol.nim`:
+   ```nim
+   type WakuMyProtocol* = ref object of LPProtocol
+     peerManager: PeerManager
+     # ... fields
+   ```
+4. Implement request handler
+5. Mount in WakuNode (`waku/node/waku_node.nim`)
+6. Add tests in `tests/waku_myprotocol/`
+7. Export module via `waku/waku_myprotocol.nim`
+
+### Adding a REST API Endpoint
+1. Define handler in `waku/rest_api/endpoint/myprotocol/`
+2. Implement endpoint following pattern:
+   ```nim
+   proc installMyProtocolApiHandlers*(
+       router: var RestRouter, node: WakuNode
+   ) =
+     router.api(MethodGet, "/waku/v2/myprotocol/endpoint") do () -> RestApiResponse:
+       # Implementation
+       return RestApiResponse.jsonResponse(data, status = Http200)
+   ```
+3. Register in `waku/rest_api/handlers.nim`
+
+### Adding Database Migration
+For message_store (SQLite):
+1. Create `migrations/message_store/NNNNN_description.up.sql`
+2. Create corresponding `.down.sql` for rollback
+3. Increment version number sequentially
+4. Test migration locally before committing
+
+For PostgreSQL: add in `migrations/message_store_postgres/`
+
+### Running Single Test During Development
+```bash
+# Build test binary
+make test tests/waku_filter_v2/test_waku_client.nim
+
+# Binary location
+./build/tests/waku_filter_v2/test_waku_client.nim.bin
+
+# Or combine
+make test tests/waku_filter_v2/test_waku_client.nim "specific test name"
+```
+
+### Debugging with Chronicles
+Set log level and filter topics:
+```bash
+nim c -r \
+  -d:chronicles_log_level=TRACE \
+  -d:chronicles_disabled_topics="eth,dnsdisc" \
+  tests/mytest.nim
+```
+
+## Key Constraints
+
+### Vendor Directory
+- Never edit files directly in vendor - it is auto-generated from git submodules
+- Always run `make update` after pulling changes
+- Managed by `nimbus-build-system`
+
+### Chronicles Performance
+- Log levels are configured at compile time for performance
+- Runtime filtering is available but should be used sparingly: `-d:chronicles_runtime_filtering=on`
+- Default sinks are optimized for production
+
+### Memory Management
+- Uses `refc` (reference counting with cycle collection)
+- Automatically enforced by the build system (hardcoded in `waku.nimble`)
+- Do not override unless absolutely necessary, as it breaks compatibility
+
+### RLN Dependencies
+- RLN code requires a Rust toolchain, which explains Rust imports in some modules
+- Pre-built `librln` libraries are checked into the repository
+
+## Quick Reference
+
+Language: Nim 2.x | License: MIT or Apache 2.0
+
+### Important Files
+- `Makefile` - Primary build interface
+- `waku.nimble` - Package definition and build tasks (called via nimbus-build-system)
+- `vendor/nimbus-build-system/` - Status's build framework
+- `waku/node/waku_node.nim` - Core node implementation
+- `apps/wakunode2/wakunode2.nim` - Main CLI application
+- `waku/factory/waku_conf.nim` - Configuration types
+- `library/libwaku.nim` - C bindings entry point
+
+### Testing Entry Points
+- `tests/all_tests_waku.nim` - All Waku protocol tests
+- `tests/all_tests_wakunode2.nim` - Node application tests
+- `tests/all_tests_common.nim` - Common utilities tests
+
+### Key Dependencies
+- `chronos` - Async framework
+- `nim-results` - Result type for error handling
+- `chronicles` - Logging
+- `libp2p` - P2P networking
+- `confutils` - CLI argument parsing
+- `presto` - REST server
+- `nimcrypto` - Cryptographic primitives
+
+Note: For specific version requirements, check `waku.nimble`.

-# nim-waku
+# Logos Messaging Nim
 
 ## Introduction
 
-The nim-waku repository implements Waku v1 and v2, and provides tools related to it.
+The logos-messaging-nim, a.k.a. lmn or nwaku, repository implements a set of libp2p protocols aimed to bring
+private communications.
 
-- A Nim implementation of the [Waku v1 protocol](https://specs.vac.dev/waku/waku.html).
-- A Nim implementation of the [Waku v2 protocol](https://specs.vac.dev/specs/waku/v2/waku-v2.html).
-- CLI applications `wakunode` and `wakunode2` that allows you to run a Waku v1 or v2 node.
-- Examples of Waku v1 and v2 usage.
+- Nim implementation of [these specs](https://github.com/vacp2p/rfc-index/tree/main/waku).
+- C library that exposes the implemented protocols.
+- CLI application that allows you to run an lmn node.
+- Examples.
 - Various tests of above.
 
-For more details on Waku v1 and v2, see their respective home folders:
+For more details see the [source code](waku/README.md)
 
-- [Waku v1](waku/v1/README.md)
-- [Waku v2](waku/v2/README.md)
+## How to Build & Run ( Linux, MacOS & WSL )
 
-## How to Build & Run
-
-These instructions are generic and apply to both Waku v1 and v2. For more
-detailed instructions, see Waku v1 and v2 home above.
+These instructions are generic. For more detailed instructions, see the source code above.
 
 ### Prerequisites
 
-* GNU Make, Bash and the usual POSIX utilities. Git 2.9.4 or newer.
-* [Rust](https://www.rust-lang.org/)
+The standard developer tools, including a C compiler, GNU Make, Bash, and Git. More information on these installations can be found [here](https://docs.waku.org/guides/nwaku/build-source#install-dependencies).
 
-More information on the installation of these can be found [here](https://github.com/status-im/nimbus#prerequisites).
+> In some distributions (Fedora linux for example), you may need to install `which` utility separately. Nimbus build system is relying on it.
+
+You'll also need an installation of Rust and its toolchain (specifically `rustc` and `cargo`).
+The easiest way to install these, is using `rustup`:
+
+```bash
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+```
 
 ### Wakunode
 
 ```bash
 # The first `make` invocation will update all Git submodules.
-# You'll run `make update` after each `git pull`, in the future, to keep those submodules up to date.
-make wakunode1 wakunode2
+# You'll run `make update` after each `git pull` in the future to keep those submodules updated.
+make wakunode2
+
+# Build with custom compilation flags. Do not use NIM_PARAMS unless you know what you are doing.
+# Replace with your own flags
+make wakunode2 NIMFLAGS="-d:chronicles_colors:none -d:disableMarchNative"
+
+# Run with DNS bootstrapping
+./build/wakunode2 --dns-discovery --dns-discovery-url=DNS_BOOTSTRAP_NODE_URL
 
 # See available command line options
-./build/wakunode --help
 ./build/wakunode2 --help
+```
+To join the network, you need to know the address of at least one bootstrap node.
+Please refer to the [Waku README](https://github.com/waku-org/nwaku/blob/master/waku/README.md) for more information.
 
-# Connect the client directly with the Status test fleet
-./build/wakunode --log-level:debug --discovery:off --fleet:test --log-metrics
-# TODO Equivalent for v2 
+For more on how to run `wakunode2`, refer to:
+- [Run using binaries](https://docs.waku.org/guides/nwaku/build-source)
+- [Run using docker](https://docs.waku.org/guides/nwaku/run-docker)
+- [Run using docker-compose](https://docs.waku.org/guides/nwaku/run-docker-compose)
+
+#### Issues
+##### WSL
+If you encounter difficulties building the project on WSL, consider placing the project within WSL's filesystem, avoiding the `/mnt/` directory.
+
+### How to Build & Run ( Windows )
+
+### Windows Build Instructions
+
+#### 1. Install Required Tools
+- **Git Bash Terminal**: Download and install from https://git-scm.com/download/win  
+- **MSYS2**:  
+  a. Download installer from https://www.msys2.org  
+  b. Install at "C:\" (default location). Remove/rename the msys folder in case of previous installation.
+  c. Use the mingw64 terminal from msys64 directory for package installation.
+
+#### 2. Install Dependencies
+Open MSYS2 mingw64 terminal and run the following one-by-one :
+```bash
+pacman -Syu --noconfirm  
+pacman -S --noconfirm --needed mingw-w64-x86_64-toolchain  
+pacman -S --noconfirm --needed base-devel make cmake upx  
+pacman -S --noconfirm --needed mingw-w64-x86_64-rust  
+pacman -S --noconfirm --needed mingw-w64-x86_64-postgresql  
+pacman -S --noconfirm --needed mingw-w64-x86_64-gcc  
+pacman -S --noconfirm --needed mingw-w64-x86_64-gcc-libs  
+pacman -S --noconfirm --needed mingw-w64-x86_64-libwinpthread-git  
+pacman -S --noconfirm --needed mingw-w64-x86_64-zlib  
+pacman -S --noconfirm --needed mingw-w64-x86_64-openssl  
+pacman -S --noconfirm --needed mingw-w64-x86_64-python
 ```
 
-### Waku Protocol Test Suite
+#### 3. Build Wakunode
+- Open Git Bash as administrator  
+- clone nwaku and cd nwaku
+- Execute: `./scripts/build_windows.sh`
+
+#### 4. Troubleshooting
+If `wakunode2.exe` isn't generated:  
+- **Missing Dependencies**: Verify with:  
+  `which make cmake gcc g++ rustc cargo python3 upx`  
+  If missing, revisit Step 2 or ensure MSYS2 is at `C:\`  
+- **Installation Conflicts**: Remove existing MinGW/MSYS2/Git Bash installations and perform fresh install
+
+### Developing
+
+#### Nim Runtime
+This repository is bundled with a Nim runtime that includes the necessary dependencies for the project.
+
+Before you can utilize the runtime you'll need to build the project, as detailed in a previous section.
+This will generate a `vendor` directory containing various dependencies, including the `nimbus-build-system` which has the bundled nim runtime.
+
+After successfully building the project, you may bring the bundled runtime into scope by running:
+```bash
+source env.sh
+```
+If everything went well, you should see your prompt suffixed with `[Nimbus env]$`. Now you can run `nim` commands as usual.
+
+### Test Suite
 
 ```bash
-# Run all the Waku v1 and v2 tests
+# Run all the Waku tests
 make test
+
+# Run a specific test file
+make test <test_file_path>
+# e.g. : make test tests/wakunode2/test_all.nim
+
+# Run a specific test name from a specific test file
+make test <test_file_path> <test_name>
+# e.g. : make test tests/wakunode2/test_all.nim "node setup is successful with default configuration"
+```
+
+### Building single test files
+
+During development it is helpful to build and run a single test file.
+To support this make has a specific target:
+
+targets:
+- `build/<relative path to your test file.nim>`
+- `test/<relative path to your test file.nim>`
+
+Binary will be created as `<path to your test file.nim>.bin` under the `build` directory .
+
+```bash
+# Build and run your test file separately
+make test/tests/common/test_enr_builder.nim
+```
+
+### Testing against `js-waku`
+Refer to [js-waku repo](https://github.com/waku-org/js-waku/tree/master/packages/tests) for instructions.
+
+## Formatting
+
+Nim files are expected to be formatted using the [`nph`](https://github.com/arnetheduck/nph) version present in `vendor/nph`.
+
+You can easily format file with the `make nph/<relative path to nim> file` command.
+For example:
+
+```
+make nph/waku/waku_core.nim
+```
+
+A convenient git hook is provided to automatically format file at commit time.
+Run the following command to install it:
+
+```shell
+make install-nph
 ```

+## Dump of things that can be improved:
+##
+## - Incoming dialed peer does not change connected state (not relying on it for now)
+## - Unclear if staticnode argument works (can enter manually)
+## - Don't trigger self / double publish own messages
+## - Integrate store protocol (fetch messages in beginning)
+## - Integrate filter protocol (default/option to be light node, connect to filter node)
+## - Test/default to cluster node connection (diff protocol version)
+## - Redirect logs to separate file
+## - Expose basic publish/subscribe etc commands with /syntax
+## - Show part of peerid to know who sent message
+## - Deal with protobuf messages (e.g. other chat protocol, or encrypted)

+## - Unclear if staticnode argument works (can enter manually)
+## - Don't trigger self / double publish own messages
+## - Test/default to cluster node connection (diff protocol version)
+## - Redirect logs to separate file
+## - Expose basic publish/subscribe etc commands with /syntax
+## - Show part of peerid to know who sent message
+## - Deal with protobuf messages (e.g. other chat protocol, or encrypted)

+# Waku - Lite Protocol Tester
+
+## Aim
+
+Testing reliability of light client protocols in different scale.
+Measure message delivery reliability and latency between light push client(s) and a filter client(s) node(s).
+
+## Concept of testing
+
+A tester node is configured either 'publisher' or 'receiver' and connects to a certain service node.
+All service protocols are disabled except for lightpush client or filter client. This way we would like to simulate
+a light client application.
+Each publisher pumps messages to the network in a preconfigured way (number of messages, frequency) while on the receiver side
+we would like to track and measure message losses, mis-ordered receives, late arrived messages and latencies.
+Ideally the tester nodes will connect to different edge of the network where we can gather more result from mulitple publishers
+and multiple receivers.
+
+Publishers are fill all message payloads with information about the test message and sender, helping the receiver side to calculate results.
+
+## Usage
+
+### Using lpt-runner
+
+For ease of use, you can clone lpt-runner repository. That will utilize previously pushed liteprotocoltester docker image.
+It is recommended to use this method for fleet testing.
+
+```bash
+git clone https://github.com/waku-org/lpt-runner.git
+cd lpt-runner
+
+# check Reame.md for more information
+# edit .env file to your needs
+
+docker compose up -d
+
+# navigate localhost:3033 to see the lite-protocol-tester dashboard
+```
+
+> See more detailed examples below.
+
+### Integration with waku-simulator!
+
+- For convenience, integration is done in cooperation with waku-simulator repository, but nothing is tightly coupled.
+- waku-simulator must be started separately with its own configuration.
+- To enable waku-simulator working without RLN currently a separate branch is to be used.
+- When waku-simulator is configured and up and running, lite-protocol-tester composite docker setup can be started.
+
+```bash
+
+# Start waku-simulator
+
+git clone https://github.com/waku-org/waku-simulator.git ../waku-simulator
+cd ../waku-simulator
+git checkout chore-integrate-liteprotocoltester
+
+# optionally edit .env file
+
+docker compose -f docker-compose-norln.yml up -d
+
+# navigate localhost:30001 to see the waku-simulator dashboard
+
+cd ../{your-repository}
+
+make  LOG_LEVEL=DEBUG liteprotocoltester
+
+cd apps/liteprotocoltester
+
+# optionally edit .env file
+
+docker compose -f docker-compose-on-simularor.yml build
+docker compose -f docker-compose-on-simularor.yml up -d
+docker compose -f docker-compose-on-simularor.yml logs -f receivernode
+```
+#### Current setup
+
+- waku-simulator is configured to run with 25 full node
+- liteprotocoltester is configured to run with 3 publisher and 1 receiver
+- liteprotocoltester is configured to run 1 lightpush service and a filter service node
+  - light clients are connected accordingly
+- publishers will send 250 messages in every 200ms with size between 1KiB and 120KiB
+- Notice there is a configurable wait before start publishing messages as it is noticed time is needed for the service nodes to get connected to full nodes from simulator
+- light clients will print report on their and the connected service node's connectivity to the network in every 20 secs.
+
+#### Test monitoring
+
+Navigate to http://localhost:3033 to see the lite-protocol-tester dashboard.
+
+### Run independently on a chosen waku fleet
+
+This option is simple as is just to run the built liteprotocoltester binary with run_tester_node.sh script.
+
+Syntax:
+`./run_tester_node.sh <path-to-liteprotocoltester-binary> <SENDER|RECEIVER> <service-node-address>`
+
+How to run from you nwaku repository:
+```bash
+cd ../{your-repository}
+
+make  LOG_LEVEL=DEBUG liteprotocoltester
+
+cd apps/liteprotocoltester
+
+# optionally edit .env file
+
+# run publisher side
+./run_tester_node.sh ../../build/liteprotocoltester SENDER [chosen service node address that support lightpush]
+
+# or run receiver side
+./run_tester_node.sh ../../build/liteprotocoltester RECEIVER [chosen service node address that support filter service]
+```
+
+#### Recommendations
+
+In order to run on any kind of network, it is recommended to deploy the built `liteprotocoltester` binary with the `.env` file and the `run_tester_node.sh` script to the desired machine.
+
+Select a lightpush service node and a filter service node from the targeted network, or you can run your own. Note down the selected peers peer_id.
+
+Run a SENDER role liteprotocoltester and a RECEIVER role one on different terminals. Depending on the test aim, you may want to redirect the output to a file.
+
+> RECEIVER side will periodically print statistics to standard output.

+
+### Specifying peer addresses
+
+Service node or bootstrap addresses can be specified in multiadress or ENR form.
+
+### Using bootstrap nodes
+
+There are multiple benefits of using bootstrap nodes. By using them liteprotocoltester will use Peer Exchange protocol to get possible peers from the network that are capable to serve as service peers for testing. Additionally it will test dial them to verify their connectivity - this will be reported in the logs and on dashboard metrics.
+Also by using bootstrap node and peer exchange discovery, litprotocoltester will be able to simulate service peer switch in case of failures. There are built in tresholds count for service peer failures (3) after service peer will be switched during the test. Also there will be max 10 trials of switching peer before test declared failed and quit.
+These service peer failures are reported, thus extending network reliability measures.
+
+### Building docker image
+
+Easiest way to build the docker image is to use the provided Makefile target.
+
+```bash
+cd <your-repository>
+make docker-liteprotocoltester
+```
+This will build liteprotocoltester from the ground up and create a docker image with the binary copied to it under image name and tag `wakuorg/liteprotocoltester:latest`.
+
+#### Building public image
+
+If you want to push the image to a public registry, you can use the jenkins job to do so.
+The job is available at https://ci.status.im/job/waku/job/liteprotocoltester/job/build-liteprotocoltester-image
+
+#### Building and deployment for infra testing
+
+For specific and continuous testing purposes we have a deployment of `liteprotocoltester` test suite to our infra appliances.
+This has its own configuration, constraints and requirements. To ease this job, image shall be built and pushed with `deploy` tag.
+This can be done by the jenkins job mentioned above.
+
+or manually by:
+```bash
+cd <your-repository>
+make DOCKER_LPT_TAG=deploy docker-liteprotocoltester
+```
+
+The image created with this method will be different from under any other tag. It prepared to run a preconfigured test suite continuously.
+It will also miss prometheus metrics scraping endpoint and grafana, thus it is not recommended to use it for general testing.
+
+#### Manually building for docker compose runs on simulator or standalone
+Please note that currently to ease testing and development tester application docker image is based on ubuntu and uses the externally pre-built binary of 'liteprotocoltester'.
+This speeds up image creation. Another dokcer build file is provided for proper build of boundle image.
+
+> `Dockerfile.liteprotocoltester` will create an ubuntu based image with the binary copied from the build directory.
+
+> `Dockerfile.liteprotocoltester.compile` will create an ubuntu based image completely compiled from source. This can be slow.
+
+#### Creating standalone runner docker image
+
+To ease the work with lite-protocol-tester, a docker image is possible to build.
+With that image it is easy to run the application in a container.
+
+> `Dockerfile.liteprotocoltester` will create an ubuntu image with the binary copied from the build directory. You need to pre-build the application.
+
+Here is how to build and run:
+```bash
+cd <your-repository>
+make liteprotocoltester
+
+cd apps/liteprotocoltester
+docker build -t liteprotocoltester:latest -f Dockerfile.liteprotocoltester ../..
+
+# alternatively you can push it to a registry
+
+# edit and adjust .env file to your needs and for the network configuration
+
+docker run --env-file .env liteprotocoltester:latest RECEIVER <service-node-peer-address>
+
+docker run --env-file .env liteprotocoltester:latest SENDER <service-node-peer-address>
+```
+
+#### Run test with auto service peer selection from a fleet using bootstrap node
+
+```bash
+
+docker run --env-file .env liteprotocoltester:latest RECEIVER <bootstrap-node-peer-address> BOOTSTRAP
+
+docker run --env-file .env liteprotocoltester:latest SENDER <bootstrap-node-peer-address> BOOTSTRAP
+```
+
+> Notice that official image is also available at harbor.status.im/wakuorg/liteprotocoltester:latest
+
+## Examples
+
+### Bootstrap or Service node selection
+
+The easiest way to get the proper bootstrap nodes for the tests from https://fleets.status.im page.
+Adjust on which fleets you would like to run the tests.
+
+> Please note that not all of them configured to support Peer Exchange protocol, those ones cannot be for bootstrap nodes for `liteprotocoltester`.
+
+### Environment variables
+You need not necessary to use .env file, although it can be more convenient.
+Anytime you can override all or part of the environment variables defined in the .env file.
+
+### Run standalone
+
+Example of running the liteprotocoltester in standalone mode on status.stagin network.
+Testing includes using bootstrap nodes to gather service peers from the network via Peer Exchange protocol.
+Both parties will test-dial all the peers retrieved with the corresponding protocol.
+Sender will start publishing messages after 60 seconds, sending 200 messages with 1 second delay between them.
+Message size will be between 15KiB and 145KiB.
+Cluster id and Pubsub-topic must be accurately set according to the network configuration.
+
+The example shows that either multiaddress or ENR form accepted.
+
+```bash
+export START_PUBLISHING_AFTER_SECS=60
+export NUM_MESSAGES=200
+export MESSAGE_INTERVAL_MILLIS=1000
+export MIN_MESSAGE_SIZE=15Kb
+export MAX_MESSAGE_SIZE=145Kb
+export SHARD=32
+export CONTENT_TOPIC=/tester/2/light-pubsub-test/fleet

+
+### Use of lpt-runner
+
+Another method is to use [lpt-runner repository](https://github.com/waku-org/lpt-runner/tree/master).
+This extends testing with grafana dashboard and ease the test setup.
+Please read the corresponding [README](https://github.com/waku-org/lpt-runner/blob/master/README.md) there as well.
+
+In this example we will run similar test as above but there will be 3 instances of publisher nodes and 1 receiver node.
+This test uses waku.sandbox fleet which is connected to TWN. This implies lower message rates due to the RLN rate limation.
+Also leave a gap of 120 seconds before starting to publish messages to let receiver side fully finish peer test-dialing.
+For TWN network it is always wise to use bootstrap nodes with Peer Exchange support.
+
+> Theoritically we can use the same bootstrap nodes for both parties, but it is recommended to use different ones to simulate different network edges, thus getting more meaningful results.
+
+```bash
+git clone https://github.com/waku-org/lpt-runner.git
+cd lpt-runner
+
+export NUM_PUBLISHER_NODES=3
+export NUM_RECEIVER_NODES=1
+export START_PUBLISHING_AFTER_SECS=120

+
+docker compose up -d
+
+# we can check logs from one or all SENDER
+docker compose logs -f --index 1 publishernode
+
+# for checking receiver side performance
+docker compose logs -f receivernode
+
+# when test completed

+# networkmonitor
+
+Monitoring tool to run in an existing `waku` network with the following features:
+
+* Keeps discovering new peers using `discv5`
+* Tracks advertised capabilities of each node as per stored in the ENR `waku` field
+* Attempts to connect to all nodes, tracking which protocols each node supports
+* Presents grafana-ready metrics showing the state of the network in terms of locations, ips, number discovered peers, number of peers we could connect to, user-agent that each peer contains, content topics and the amount of rx messages in each one.
+* Metrics are exposed through prometheus metrics but also with a custom rest api, presenting detailed information about each peer. These metrics are exposed via a rest api.
+
+## Usage

+
+## Metrics
+
+Metrics are divided into two categories:
+
+* Prometheus metrics, exposed as i.e. gauges.
+* Custom metrics, used for unconstrained labels such as peer information or content topics.
+  - These metrics are not exposed through prometheus because since they are unconstrained, they can end up breaking the backend, as a new datapoint is generated for each one and it can reach up a point where is too much to handle.
+
+### Prometheus Metrics
+
+The following metrics are available. See `http://localhost:8008/metrics`
+
+* `peer_type_as_per_enr`: Number of peers supporting each capability according to the ENR (Relay, Store, Lightpush, Filter)
+* `peer_type_as_per_protocol`: Number of peers supporting each protocol, after a successful connection)
+* `peer_user_agents`: List of useragents found in the network and their count
+
+Other relevant metrics reused from `nim-eth`:
+
+* `routing_table_nodes`: Inherited from nim-eth, number of nodes in the routing table
+* `discovery_message_requests_outgoing_total`: Inherited from nim-eth, number of outgoing discovery requests, useful to know if the node is actively looking for new peers
+
+### Custom Metrics
+
+The following endpoints are available:
+
+* `http://localhost:8009/allpeersinfo`: json list of all peers with extra information such as ip, location, supported protocols and last connection time.
+* `http://localhost:8009/contenttopics`: content topic messages and its message count.

+# Sonda
+
+Sonda is a tool to monitor store nodes and measure their performance.
+
+It works by running a `nwaku` node, publishing a message from it every fixed interval and performing a store query to all the store nodes we want to monitor to check they respond with the last message we published.
+
+## Instructions
+
+1. Create an `.env` file which will contain the configuration parameters.
+    You can start by copying `.env.example` and adapting it for your use case
+
+    ```
+    cp .env.example .env
+    ${EDITOR} .env
+    ```
+
+    The variables that have to be filled for Sonda are
+
+    ```
+    CLUSTER_ID=
+    SHARD=
+    # Comma separated list of store nodes to poll
+    STORE_NODES=
+    # Wait time in seconds between two consecutive queries
+    QUERY_DELAY=
+    # Consecutive successful store requests to consider a store node healthy
+    HEALTH_THRESHOLD=
+    ```
+
+2. If you want to query nodes in `cluster-id` 1, then you have to follow the steps of registering an RLN membership. Otherwise, you can skip this step.
+
+    For it, you need:
+    * Ethereum Linea Sepolia WebSocket endpoint. Get one free from [Infura](https://linea-sepolia.infura.io/).
+    * Ethereum Linea Sepolia account with minimum 0.01ETH. Get some [here](https://docs.metamask.io/developer-tools/faucet/).
+    * A password to protect your rln membership.
+
+    Fill the `RLN_RELAY_ETH_CLIENT_ADDRESS`, `ETH_TESTNET_KEY` and `RLN_RELAY_CRED_PASSWORD` env variables and run
+
+    ``` 
+    ./register_rln.sh
+    ```
+
+3. Start Sonda by running
+   
+    ```
+    docker-compose up -d
+    ```
+
+4. Browse to http://localhost:3000/dashboards and monitor the performance
+
+    There's two Grafana dashboards: `nwaku-monitoring` to track the stats of your node that is publishing messages and performing queries, and `sonda-monitoring` to monitor the responses of the store nodes.
