 Run the `npm run deploy:test` command to deploy the contract, or you can refer to the `. /tests` folder for test cases.
 
+### Work with Web UI
+
+To use the contract with the Web UI, we need to run the hardhat network locally and export the `ABI` of the contracts in the directory where the UI is located, which by default is: `../website/contracts/`.
+
+To run the hardhat network locally with contracts deployed:
+
+```bash
+$ npm start
+$ npm run deploy:localhost
+```
+
+And, add the `MulticallV1` contract address to `.env.local` of the Web UI project without `0x` prefix. (Make sure to replace with the address you just deployed, not the sample one)

+```
+NEXT_PUBLIC_LOCALHOST_MULTICALL_ADDRESS=Cf7Ed3AccA5a467e9e704C703E8D87F634fB0Fc9
