-# Sample Hardhat Project
+# Agora Blockchain Project
 
-This project demonstrates a basic Hardhat use case. It comes with a sample contract, a test for that contract, and a Hardhat Ignition module that deploys that contract.
+This project contains the smart contracts for Agora Blockchain, built using **Foundry**.
 
-Try running some of the following tasks:
+## Getting Started
+
+### Prerequisites
+
+- [Foundry](https://book.getfoundry.sh/getting-started/installation)
+
+### Build
+
+```shell
+forge build
+```
+
+### Test
+
+```shell
+forge test
+```
+
+### Format
+
+```shell
+forge fmt
+```
+
+### Local Node
+
+Start a local testnet:
+
+```shell
+anvil
+```
+
+### Deploy
+
+To deploy contracts, use `forge create` or `forge script`.
 
 ```shell
-npx hardhat help
-npx hardhat test
-REPORT_GAS=true npx hardhat test
-npx hardhat node
-npx hardhat ignition deploy ./ignition/modules/Lock.js
+forge script script/MyScript.s.sol --rpc-url <your_rpc_url> --private-key <your_private_key>
