 Create parallel reality of your Substrate network.
 
-## Run
+## Install
 
-Make sure you have setup Rust environment.
+Make sure you have setup Rust environment (>= 1.64).
 
+- Clone repository with submodules ([smoldot](https://github.com/paritytech/smoldot))
+  - `git clone --recurse-submodules https://github.com/AcalaNetwork/chopsticks.git && cd chopsticks`
 - Install deps
   - `yarn`
 - Build wasm
   - `yarn build-wasm`
-- Run nodejs runner
-  - `yarn start run-block --endpoint=wss://acala-rpc-2.aca-api.network/ws`
 
-Connect to the rpc via localhost:8000 and you may be able to submit transaction and it will be executed in parallel reality.
+## Run
 
-NOTE: subscriptions are not yet implemented so you will need to refresh to see new blocks.
+- Replay latest block
+
+  - `yarn start run-block --endpoint=wss://acala-rpc-2.aca-api.network/ws`
+  - This will replay the last block and print out the changed storages
 
-NOTE2: this currently takes ~half minute to produce a new block.
+- Run a test node
+  - `yarn start dev --endpoint=wss://acala-rpc-2.aca-api.network/ws`
+  - You have a test node running at `ws://localhost:8000`
+  - You can use [Polkadot.js Apps](https://polkadot.js.org/apps/) to connect to this node
+  - Submit any transaction to produce a new block in the in parallel reality
 
 Next step:
 
-- Implements subscription
 - Disable signature verification
 - API for arbitrary storage override
-- Compile the rust part into wasm
