+# Lottery Randomness with ChainLink
+
+## Usage
+
+### Pre Requisites
+
+Before being able to run any command, you need to create a `.env` file and set a BIP-39 compatible mnemonic as an
+environment variable. You can follow the example in `.env.example`. If you don't already have a mnemonic, you can use
+this [website](https://iancoleman.io/bip39/) to generate one.
+
+Then, proceed with installing dependencies:
+
+```sh
+$ yarn install
+```
+
+### Compile
+
+Compile the smart contracts with Hardhat:
+
+```sh
+$ yarn compile
+```
+
+### TypeChain
+
+Compile the smart contracts and generate TypeChain bindings:
+
+```sh
+$ yarn typechain
+```
+
+### Test
+
+Run the tests with Hardhat:
+
+```sh
+$ yarn test
+```
+
+### Lint Solidity
+
+Lint the Solidity code:
+
+```sh
+$ yarn lint:sol
+```
+
+### Lint TypeScript
+
+Lint the TypeScript code:
+
+```sh
+$ yarn lint:ts
+```
+
+### Coverage
+
+Generate the code coverage report:
+
+```sh
+$ yarn coverage
+```
+
+### Report Gas
+
+See the gas usage per unit test and average gas per method call:
+
+```sh
+$ REPORT_GAS=true yarn test
+```
+
+### Clean
+
+Delete the smart contract artifacts, the coverage reports and the Hardhat cache:
+
+```sh
+$ yarn clean
+```
+
+### Deploy
+
+Deploy the contracts to Hardhat Network:
+
+```sh
+$ yarn deploy --greeting "Bonjour, le monde!"
+```
+
+### Fix husky not executable
+
+```sh
+chmod ug+x .husky/*
+chmod ug+x .git/hooks/*
+```
