+# zkSync Hardhat project
+
+This project was scaffolded with [zksync-cli](https://github.com/matter-labs/zksync-cli).
+
+## Project structure
+
+- `/contracts`: smart contracts.
+- `/deploy`: deployment and contract interaction scripts.
+- `/test`: test files
+- `hardhat.config.ts`: configuration file.
+
+## Commands
+
+- `yarn hardhat compile` will compile the contracts.
+- `yarn run deploy` will execute the deployment script `/deploy/deploy-greeter.ts`. Requires [environment variable setup](#environment-variables).
+- `yarn run greet` will execute the script `/deploy/use-greeter.ts` which interacts with the Greeter contract deployed.
+- `yarn test`: run tests. **Check test requirements below.**
+
+Both `yarn run deploy` and `yarn run greet` are configured in the `package.json` file and run `yarn hardhat deploy-zksync`.
+
+### Environment variables
+
+In order to prevent users to leak private keys, this project includes the `dotenv` package which is used to load environment variables. It's used to load the wallet private key, required to run the deploy script.
+
+To use it, rename `.env.example` to `.env` and enter your private key.
+
+```
+WALLET_PRIVATE_KEY=123cde574ccff....
+```
+
+### Local testing
+
+In order to run test, you need to start the zkSync local environment. Please check [this section of the docs](https://v2-docs.zksync.io/api/hardhat/testing.html#prerequisites) which contains all the details.
+
+If you do not start the zkSync local environment, the tests will fail with error `Error: could not detect network (event="noNetwork", code=NETWORK_ERROR, version=providers/5.7.2)`
