 ## Examples
 
-Check out the [examples](./examples) directory for usage patterns:
+```typescript
+import { type Device, Tappy } from "@lycorp-jp/tappy";
+import { PuppeteerAdapter } from "@lycorp-jp/tappy/adapters";
+import puppeteer from "puppeteer";
+
+const browser = await puppeteer.launch();
+const page = await browser.newPage();
+
+const adapter = new PuppeteerAdapter(page);
+const tappy = new Tappy(adapter);
+
+// For accurate device specs, refer to: https://www.ios-resolution.com/
+const device: Device = {
+  name: "iPhone 12 Pro",
+  width: 390,
+  height: 844,
+  scale: 3,
+  ppi: 460,
+};
+
+const result = await tappy.analyze("https://example.com", device);
+
+console.log(result.elements);
+// This contains information about all analyzed tappable elements
+// Example output:
+// [
+//   {
+//     width: 136.984375,      // Element width in CSS pixels
+//     height: 18,             // Element height in CSS pixels
+//     left: 32,               // X position from left edge
+//     top: 200.875,           // Y position from top edge
+//     tapSuccessRate: 0.8497559260608007  // Success rate (0-1, where 1 is 100%)
+//   }
+// ]
