+# Web3.js + React Minimal dApp Template
+
+This project is a minimal template for using [Web3.js](https://web3js.org/) with
+[React](https://react.dev/).
+
+- [Web3.js Docs](https://docs.web3js.org/)
+- [React Docs](https://react.dev/learn)
+
+This project was bootstrapped with
+[Create React App](https://github.com/facebook/create-react-app).
+
+## Getting Started
+
+Install the project dependencies with a dependency manager like npm or Yarn. Use
+`npm start` to start a local development server and navigate to
+http://localhost:3000 to view the dApp.
+
+## Project Design
+
+This project defines a service in
+[./src/web3/web3-service.ts](./src/web3/web3-service.ts) that exposes an
+instance of the [`Web3` class](https://docs.web3js.org/api/web3/class/Web3) and
+an [EIP-1193](https://eips.ethereum.org/EIPS/eip-1193) provider, if present. If
+the provider is present, it's used by the `Web3` instance to communicate with
+the network and the service registers a
+[`chainChanged` handler](https://docs.metamask.io/wallet/reference/provider-api/#chainchanged)
+that reloads the page. Refer to [./src/App.tsx](./src/App.tsx) for an example of
+using the service.
