+# Chain Signatures Contract on Ethereum
+
+## Overview
+
+This repository contains the Solidity code for the Chain Signatures contract, which is deployed on the Ethereum blockchain.
+
+## Setup
+
+To setup the project, you can use the following command:
+
+```bash
+npm install
+```
+
+## Compile
+
+To compile the contract, you can use the following command:
+
+```bash
+npx hardhat compile
+```
+
+## Testing
+
+To unit test the contract, you can use the following command:
+
+```bash
+npx hardhat test
+```
+
+To do a quick end-to-end test, you can use the following command:
+```bash
+npx hardhat node
+```
+
+Then in a separate terminal, you can run the following command to deploy the contract:
+```bash
+npx hardhat ignition deploy ignition/modules/chainSignatures.js --network localhost
+```
+
+Then run this command to run the responder (mpc node expects to be this role):
+
+```bash
+npx hardhat run scripts/responder.js
+```
+
+Then in a separate terminal, run the following command to execute the `sign.js` script (mpc client expects to be this role):
+```bash
+npx hardhat run scripts/sign.js
+```
