+# BOLD App
+
+## Preview
+
+<https://liquity2.vercel.app/>
+
+## Requirements
+
+- [Node.js](https://nodejs.org/)
+- [pnpm](https://pnpm.io/)
+
+## Setup
+
+```sh
+git clone git@github.com:liquity/bold.git
+cd bold/frontend
+pnpm install
+```
+
+## How to develop
+
+Run the Hardhat Network local node:
+
+```sh
+cd bold/contracts
+ACCOUNTS_BALANCE=1000 pnpm hardhat node # ACCOUNTS_BALANCE=1000 is optional but nicer than the default values in the UI
+```
+
+Deploy the contracts:
+
+```sh
+cd bold/contracts
+pnpm hardhat run --network localhost utils/deploymentDev.js
+```
+
+Copy the addresses of the deployed contracts to the `.env.local` file.
+
+Run the development server:
+
+```sh
+cd bold/frontend
+pnpm dev
+```
+
+You can now open <http://localhost:3000/> in your browser.
+
+See also `contracts/hardhatAccountsList2k.js` to import the accounts into MetaMask (the deployment script opens troves for the first six accounts).
+
+## Scripts
+
+```sh
+pnpm dev                    # run the development server
+pnpm build                  # build the static app in out/
+pnpm fmt                    # format the code
+pnpm lint                   # lint the code
+pnpm test                   # run the tests
+pnpm update-liquity-abis    # build the contracts and update the ABIs
+```
+
+## Environment
+
+Create `.env.local` from the `.env` file and fill in the required values (see the description of each variable below).
+
+```sh
+cp .env .env.local
+```
+
+See [./src/env.ts](./src/env.ts) for details about how the environment variables are being imported by the app.
+

+- `1` (mainnet)
