-## Foundry
+# Simple Chainlink CCIP
 
-**Foundry is a blazing fast, portable and modular toolkit for Ethereum application development written in Rust.**
+This is a simple Chainlink CCIP that transfer the ERC20 Token from Sepolia to Amoy testnet
 
-Foundry consists of:
+# Getting Started
 
--   **Forge**: Ethereum testing framework (like Truffle, Hardhat and DappTools).
--   **Cast**: Swiss army knife for interacting with EVM smart contracts, sending transactions and getting chain data.
--   **Anvil**: Local Ethereum node, akin to Ganache, Hardhat Network.
--   **Chisel**: Fast, utilitarian, and verbose solidity REPL.
+## Requirements
 
-## Documentation
+- [git](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git)
+  - You'll know you did it right if you can run `git --version` and you see a response like `git version x.x.x`
+- [foundry](https://getfoundry.sh/)
+  - You'll know you did it right if you can run `forge --version` and you see a response like `forge 0.2.0 (816e00b 2023-03-16T00:05:26.396218Z)`
 
-https://book.getfoundry.sh/
+## Quickstart
 
-## Usage
+```
+git clone https://github.com/cqlyj/simple-chainlink-ccip.git
+cd simple-chainlink-ccip
+make
+```
 
-### Build
+# Usage
 
-```shell
-$ forge build
+1. Set up your environment variables:
+
+```bash
+cp .env.example .env
 ```
 
-### Test
+2. Fill in the `.env` file with your own values. And also replace the address anywhere you see in files with your own address.
+3. Before running the demo, you need to set up your wallet:
 
-```shell
-$ forge test
+```bash
+cast wallet import YOUR_ACCOUNT_NAME --interactive
 ```
 
-### Format
+Here I would call it `burner`, and a interactive prompt will show as below:
 
-```shell
-$ forge fmt
+```bash
+    Enter private key:
+    Enter password:
+    `your-account-name` keystore was saved successfully. Address: address-corresponding-to-private-key
 ```
 
-### Gas Snapshots
+Please keep in mind the password you entered, this will be needed for you moving forward with the private key.
+
+And if you change the name from `burner` to something else, you need to update in the `Makefile` as well. Also the `sender` needs to be your address.
 
-```shell
-$ forge snapshot
+```diff
+deploy:
+-	@forge script script/DeployTokenTransfer.s.sol:DeployTokenTransfer --rpc-url $(SEPOLIA_RPC_URL) --account burner --sender 0xFB6a372F2F51a002b390D18693075157A459641F --broadcast --verify --verifier blockscout --verifier-url https://eth-sepolia.blockscout.com/api/ -vvvv
++   @forge script script/DeployTokenTransfer.s.sol:DeployTokenTransfer --rpc-url $(SEPOLIA_RPC_URL) --account YOUR_ACCOUNT_NAME --sender YOUR_ADDRESS --broadcast --verify --verifier blockscout --verifier-url https://eth-sepolia.blockscout.com/api/ -vvvv
 ```
 
-### Anvil
+Same for any other command in `Makefile` which ask for your account name and sender addresses.
 
-```shell
-$ anvil
-```
+4. Also update the address in `script/TransferTokenPayNative.s.sol` and `script/WithdrawBalance.s.sol` with your own address.
 
-### Deploy
+In `script/TransferTokenPayNative.s.sol`:
 
-```shell
-$ forge script script/Counter.s.sol:CounterScript --rpc-url <your_rpc_url> --private-key <your_private_key>
+```diff
+address public constant RECEIVER =
+-        0xFB6a372F2F51a002b390D18693075157A459641F;
++        YOUR_ADDRESS;
 ```
 
-### Cast
+In `script/WithdrawBalance.s.sol`:
 
-```shell
-$ cast <subcommand>
+```diff
+address public constant BENEFICIARY =
+-        0xFB6a372F2F51a002b390D18693075157A459641F;
++        YOUR_ADDRESS;
 ```
 
-### Help
+5. Run the demo:
 
-```shell
-$ forge --help
-$ anvil --help
-$ cast --help
+```bash
+make demo
 ```
+
+Wait for about 20 mins, and you will get the token in your Amoy testnet account.
