+This template project demonstrates how to implement a simple token faucet and expose it with a Web UI using Next.js.
+
+## Getting Started
+
+### Install
+
+```
+npm install
+
+```
+
+### Deploy the token faucet contract
+
+```bash
+# In this case devnet
+npx @alephium/cli deploy -n devnet
+```
+
+This will compile and deploy the token faucet contracts to all of the
+4 groups on devnet.
+
+### Run the development server
+
+```bash
+npm run dev
+# or
+yarn dev
+```
+
+Open [http://localhost:3000](http://localhost:3000) with your browser
+to see the token faucet application.
+
+Download the [Alephium Extension Wallet](https://github.com/alephium/extension-wallet)
+to interact with the application.
