+# `checkAndSignAuthMessage` Example ✍️
+
+This is an example web app that shows how you can easily obtain an `AuthSig` using the `checkAndSignAuthMessage` function.
+
+When the function is called, it prompts a wallet selection pop-up in the user's browser. Once the user's wallet is connected, the user is asked to sign a message, thereby confirming the ownership of their crypto address. The `AuthSig`` is then generated, which includes the signature of the user's signed message.
+
+## 💻 Getting Started
+
+First, run the development server:
+
+```bash
+npm run dev
+# or
+yarn dev
+# or
+pnpm dev
+```
+
+Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
