+# Introduction
+
+`ncli` is a set of low level / debugging tools to interact with the nimbus [beacon chain specification](https://github.com/ethereum/eth2.0-specs/tree/dev/specs) implementation, simliar to [zcli](https://github.com/protolambda/zcli). With it, you explore SSZ, make state transitions and compute hash tree roots.
+
+# Tools
+
+* transition: Perform state transition given a pre-state and a block to apply (both in SSZ format)
+* signing_root/hash_tree_root: Print tree root of an SSZ object
+* pretty: Pretty-print SSZ object as JSON
+
+# Building
+
+Follow the instructions from [nim-beacon-chain](../README.md)
+
+```bash
+git clone https://github.com/status-im/nim-beacon-chain.git
+cd nim-beacon-chain
+make
+```
+
+# Usage
+
+```
+# Build with minimal config
+../env.sh nim c ncli_transition -d:const_preset=minimal
+# Build with mainnet config
+../env.sh nim c ncli_transition -d:const_preset=mainnet
+
+# Run..
+./ncli_transition --help
+```
