+## CCIP GYD Bridge
+
+The code is based on the [zkEVM DAI bridge](https://github.com/pyk/zkevm-dai)
+
+### Introduction
+
+Bridged GYD implementation consists of two smart contracts:
+
+1. **GydL1Escrow**: This contract is deployed on Ethereum mainnet.
+2. **L2Gyd**: This contract is deployed on L2s.
+
+The user can do the following:
+
+1. Bridge GYD from Ethereum mainnet to an L2 via `GydL1Escrow` contract.
+2. Bridge GYD from an L2 to Ethereum mainnet via `L2Gyd` contract.
+
+## Get started
+
+### Requirements
+
+This repository uses foundry. You can install foundry via
+[foundryup](https://book.getfoundry.sh/getting-started/installation).
+
+### Setup
+
+Clone the repository:
+
+```sh
+git clone git@github.com:gyrostable/ccip-gyd.git
+cd ccip-gyd/
+```
+
+Install the dependencies:
+
+```sh
+forge install
+```
+
+### Tests
+
+Create `.env` with the following contents:
+
+```
+ETH_RPC_URL=""
+ARBITRUM_RPC_URL="https://arb1.arbitrum.io/rpc"
+ETHERSCAN_API_KEY=""
+```
+
+Use the following command to run the test:
+
+```sh
+forge test
+```
+
+> **Note**
+> You can set `ETHERSCAN_API_KEY` to helps you debug the call trace.
+
+## Deployment
+
+Deployment scripts are located in the [`script`](./script/) directory.
