+# Web3-Onboard + NextJs
+
+
+
+This should serve as a reference example for how to integrate Web3-Onboard with a NextJs app! 🙌
+
+The [web3-onboard.ts](./web3-onboard.ts) file contains everything necessary to configure and initialize Web3-Onboard.
+
+Here's the TL;DR
+
+1. Wrap the provider
+
+[_app.tsx](./pages/_app.tsx)
+```react
+export default function App({ Component, pageProps }: AppProps) {
+  return (
+    <Web3OnboardProvider web3Onboard={web3Onboard}>
+      <Component {...pageProps} />
+    </Web3OnboardProvider>
+  )
+}
+```
+
+2. Import and Setup
+
+[index.tsx](./pages/index.tsx)
+```ts
+// ...
+export default function Home() {
+  const [{ wallet, connecting }, connect, disconnect] = useConnectWallet()
+
+  // create an ethers provider
+  let ethersProvider
+
+  if (wallet) {
+    ethersProvider = new ethers.providers.Web3Provider(wallet.provider, 'any')
+  }
+  
+  return (/* ... */)
+}
+```
+
+3. Add the wallet connect button
+
+[index.tsx](./pages/index.tsx)
+```html
+<button
+    style={buttonStyles}
+    disabled={connecting}
+    onClick={() => (wallet ? disconnect(wallet) : connect())}
+>
+    {connecting ? 'Connecting' : wallet ? 'Disconnect' : 'Connect'}
+</button>
+```
+
+And that's it! 🎉 You should be well on your way to **buidl**ing that next killer dApp!
+
+--- 
+
+This is a [Next.js](https://nextjs.org/) project bootstrapped with [`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app).
+
+## Getting Started
+
+First, run the development server:
+
+```bash
+npm run dev
+# or
+yarn dev
+```
+
+Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+
+You can start editing the page by modifying `pages/index.tsx`. The page auto-updates as you edit the file.
+
+[API routes](https://nextjs.org/docs/api-routes/introduction) can be accessed on [http://localhost:3000/api/hello](http://localhost:3000/api/hello). This endpoint can be edited in `pages/api/hello.ts`.
+
+The `pages/api` directory is mapped to `/api/*`. Files in this directory are treated as [API routes](https://nextjs.org/docs/api-routes/introduction) instead of React pages.
+
+## Learn More
+
+To learn more about Next.js, take a look at the following resources:
+
+- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
+- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
+
+You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js/) - your feedback and contributions are welcome!
+
+## Deploy on Vercel
+
+The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
+
+Check out our [Next.js deployment documentation](https://nextjs.org/docs/deployment) for more details.
