 CI/CD workflow fails if the unit test code coverage threshold (**80% of lines of code**) for scripts is not met. 
 
+## Run the localhost development network
+
+Hardhat framework provides a local blockchain network that lives in memory, that is useful to test local developments.
+To start the network run the command:
+
+`npm run node:start`
+
+## Compile the smart contracts
+
+Run the command: `npm run compile`
+
+## Deploy the smart contract
+
+The smart contracts deploy process is managed, under the hood, by [Ignition](https://hardhat.org/ignition/docs/getting-started#overview).
+
+To deploy smart contract instances run the command:
+
+`npm run deploy-contract <ignition-module-path> <network>`
+
+Ignition will deploy the instances of the smart contract following the logic specified in the ignition module.
+
+To deploy to a specific network (e.g. mainnet, sepora), the network must be configured in the `hardhat.config.ts` file.
+
+For the local network the parameter to pass is `localhost`, there is no need to configure the local network.
