+# Waku Browser Tests
+
+This project provides a system for testing the Waku SDK in a browser environment.
+
+## Architecture
+
+The system consists of:
+
+1. **Headless Web App**: A simple web application (in the `@waku/headless-tests` package) that loads the Waku SDK and exposes shared API functions.
+2. **Express Server**: A server that communicates with the headless app using Playwright.
+3. **Shared API**: TypeScript functions shared between the server and web app.
+
+## Setup
+
+1. Install dependencies:
+
+```bash
+# Install main dependencies
+npm install
+
+# Install headless app dependencies
+cd ../headless-tests
+npm install
+cd ../browser-tests
+```
+
+2. Build the application:
+
+```bash
+npm run build
+```
+
+This will:
+- Build the headless web app using webpack
+- Compile the TypeScript server code
+
+## Running
+
+Start the server with:
+
+```bash
+npm run start:server
+```
+
+This will:
+1. Serve the headless app on port 8080
+2. Start a headless browser to load the app
+3. Expose API endpoints to interact with Waku
+
+## API Endpoints
+
+- `GET /info`: Get information about the Waku node
+- `GET /debug/v1/info`: Get debug information from the Waku node
+- `POST /push`: Push a message to the Waku network (legacy)
+- `POST /lightpush/v1/message`: Push a message to the Waku network (Waku REST API compatible)
+- `POST /admin/v1/create-node`: Create a new Waku node (requires networkConfig)
+- `POST /admin/v1/start-node`: Start the Waku node
+- `POST /admin/v1/stop-node`: Stop the Waku node
+- `POST /admin/v1/peers`: Dial to specified peers (Waku REST API compatible)
+- `GET /filter/v2/messages/:contentTopic`: Subscribe to messages on a specific content topic using Server-Sent Events (Waku REST API compatible)
+- `GET /filter/v1/messages/:contentTopic`: Retrieve stored messages from a content topic (Waku REST API compatible)
+
+### Example: Pushing a message with the legacy endpoint
+
+```bash
+curl -X POST http://localhost:3000/push \
+  -H "Content-Type: application/json" \
+  -d '{"contentTopic": "/toy-chat/2/huilong/proto", "payload": [1, 2, 3]}'
+```
+
+### Example: Pushing a message with the Waku REST API compatible endpoint
+
+```bash
+curl -X POST http://localhost:3000/lightpush/v1/message \
+  -H "Content-Type: application/json" \
+  -d '{
+    "pubsubTopic": "/waku/2/rs/0/0",
+    "message": {
+      "payload": "SGVsbG8sIFdha3Uh",
+      "contentTopic": "/toy-chat/2/huilong/proto",
+      "timestamp": 1712135330213797632
+    }
+  }'
+```
+
+### Example: Executing a function
+
+```bash
+curl -X POST http://localhost:3000/execute \
+  -H "Content-Type: application/json" \
+  -d '{"functionName": "getPeerInfo", "params": []}'
+```
+
+### Example: Creating a Waku node
+
+```bash
+curl -X POST http://localhost:3000/admin/v1/create-node \
+  -H "Content-Type: application/json" \
+  -d '{
+    "defaultBootstrap": true,
+    "networkConfig": {
+      "clusterId": 1,
+      "shards": [0, 1]
+    }
+  }'
+```
+
+### Example: Starting and stopping a Waku node
+
+```bash
+# Start the node
+curl -X POST http://localhost:3000/admin/v1/start-node
+
+# Stop the node
+curl -X POST http://localhost:3000/admin/v1/stop-node
+```
+
+### Example: Dialing to specific peers with the Waku REST API compatible endpoint
+
+```bash
+curl -X POST http://localhost:3000/admin/v1/peers \
+  -H "Content-Type: application/json" \
+  -d '{
+    "peerMultiaddrs": [
+      "/ip4/127.0.0.1/tcp/8000/p2p/16Uiu2HAm4v8KuHUH6Cwz3upPeQbkyxQJsFGPdt7kHtkN8F79QiE6"]
+    ]
+  }'
+```
+
+### Example: Dialing to specific peers with the execute endpoint
+
+```bash
+curl -X POST http://localhost:3000/execute \
+  -H "Content-Type: application/json" \
+  -d '{
+    "functionName": "dialPeers", 
+    "params": [
+      ["/ip4/127.0.0.1/tcp/8000/p2p/16Uiu2HAm4v8KuHUH6Cwz3upPeQbkyxQJsFGPdt7kHtkN8F79QiE6"]
+    ]
+  }'
+```
+
+### Example: Subscribing to a content topic with the filter endpoint
+
+```bash
+# Open a persistent connection to receive messages as Server-Sent Events
+curl -N http://localhost:3000/filter/v2/messages/%2Ftoy-chat%2F2%2Fhuilong%2Fproto
+
+# You can also specify clustering options
+curl -N "http://localhost:3000/filter/v2/messages/%2Ftoy-chat%2F2%2Fhuilong%2Fproto?clusterId=0&shard=0"
+```
+
+### Example: Retrieving stored messages from a content topic
+
+```bash
+# Get the most recent 20 messages
+curl http://localhost:3000/filter/v1/messages/%2Ftoy-chat%2F2%2Fhuilong%2Fproto
+
+# Get messages with pagination and time filtering
+curl "http://localhost:3000/filter/v1/messages/%2Ftoy-chat%2F2%2Fhuilong%2Fproto?pageSize=10&startTime=1712000000000&endTime=1713000000000&ascending=true"
+```
+
+## Extending
+
+To add new functionality:
+
+1. Add your function to `src/api/shared.ts`
+2. Add your function to the `API` object in `src/api/shared.ts`
+3. Use it via the server endpoints 
+
+### Example: Dialing to specific peers
+
+```bash
+curl -X POST http://localhost:3000/execute \
+  -H "Content-Type: application/json" \
+  -d '{
+    "functionName": "dialPeers", 
+    "params": [
+      ["/ip4/127.0.0.1/tcp/8000/p2p/16Uiu2HAm4v8KuHUH6Cwz3upPeQbkyxQJsFGPdt7kHtkN8F79QiE6"]
+    ]
+  }'
+```

+# Waku Headless Tests
+
+This package contains a minimal browser application used for testing the Waku SDK in a browser environment. It is used by the browser-tests package to run end-to-end tests on the SDK.
+
+## Usage
+
+### Build the app
+
+```bash
+npm run build
+```
+
+### Start the app
+
+```bash
+npm start
+```
+
+This will start a server on port 8080 by default.
+
+## Integration with browser-tests
+
+This package is designed to be used with the browser-tests package to run end-to-end tests on the SDK. It exposes the Waku API via a global object in the browser.
