+## Deploying contracts to test networks
+
+A deploy script is included in this hardhat project to deploy a contract directly to a network.
+To deploy the contracts to different networks:
+```
+npx hardhat run --network <network-name> scripts/deploy.ts
+```
+
+Configuration for various `<network-name>`s above are setup in the [hardhat config](./hardhat.config.ts).

 ## Production compiling & Ethermint JSON
 
 Ethermint uses its own json format that includes the ABI and bytecode in a single file. The bytecode should have no `0x` prefix and should be under the property name `bin`. This structure is built from the compiled code with `npm ethermint-json`.
