-# Sample Hardhat Project
+# Celo Composer - MiniPay Template | Hardhat
 
-This project demonstrates a basic Hardhat use case. It comes with a sample contract, a test for that contract, and a script that deploys that contract.
+## How to use
 
-Try running some of the following tasks:
+1. Create a copy of `.env.example` and rename it to `.env`.
 
-```shell
-npx hardhat help
-npx hardhat test
-REPORT_GAS=true npx hardhat test
-npx hardhat node
-npx hardhat run scripts/deploy.ts
+   1. For the **smart contract deployment** you will need the `PRIVATE_KEY` set in `.env`. **Never** use a wallet with real funds for development. Always have a separate wallet for testing. 
+   2. For the **smart contract verification** you will need a [Celoscan API Key](https://celoscan.io/myapikey) `CELOSCAN_API_KEY` set in `.env`.
+
+2. Compile the contract 
+
+```bash
+npx hardhat compile
+```
+
+3. Deploy the contract
+
+Make sure your wallet is funded when deploying to testnet or mainnet. You can get test tokens for deploying it on Alfajores from the [Celo Faucet](https://faucet.celo.org/alfajores).
+
+```bash
+npx hardhat ignition deploy ./ignition/modules/MiniPay.ts --network <network-name>
+```
+
+On Alfajores
+
+```bash
+npx hardhat ignition deploy ./ignition/modules/MiniPay.ts --network alfajores
+```
+
+
+On Celo Mainnet
+
+```bash
+npx hardhat ignition deploy ./ignition/modules/MiniPay.ts --network celo
+```
+
+4. Verify the contract
+
+For Alfajores (Testnet) Verification
+
+```bash
+npx hardhat verify <CONTRACT_ADDRESS>  <CONSTRUCTOR_ARGS> --network alfajores
+```
+
+For the Lock.sol contract that could look like this:
+
+```bash
+npx hardhat verify 0xF9316Ce3E661D704000bCDDA925766Bf7F09fF5B 0x1724707c52de2fa65ad9c586b5d38507f52D3c06  --network alfajores
+```
+
+For Celo Mainnet Verification
+
+```bash
+npx hardhat verify <CONTRACT_ADDRESS>  <CONSTRUCTOR_ARGS> --network celo
 ```
+
+Check the file `hardhat.config.js` for Celo specific hardhat configuration.
