+#### 2. Deploy to a Local Network
+
+The complete deployment is multi-chain, so a deployment to the local network can only simulate either the Home chain or the Foreign chain.
+Currently the scripts support only deploying the HomeChain contracts to the local network.
+
+**Shell 1: the node**
+
+```bash
+yarn hardhat node --tags nothing
+```
+
+**Shell 2: the deploy script**
+
+```bash
+yarn hardhat deploy --network localhost --tags HomeChain
+```
+
 #### 2. Deploy to Public Testnets
 
 ```bash
-yarn deploy:staging # to deploy to L1/L2 testnet
-# yarn deploy:production # to deploy to L1/L2 mainnet
+# To deploy on L2 only
+yarn hardhat deploy --network arbitrumRinkeby --tags HomeChain
+
+# To deploy on L1 only
+yarn hardhat deploy --network rinkeby --tags ForeignChain
+
+# To deploy both L1 and L2
+yarn deploy:staging
 ```
 
 The deployed addresses should be output to the screen after the deployment is complete.
