+// NOTE: That if you are using the devtools and enable Edge Runtime, you will need to copy the devtools
+// static assets to the public folder. You can do this by adding a script to your package.json:
+// ```json
+// {
+//   scripts: {
+//     "copy-static": "cp -r ./node_modules/frog/_lib/ui/.frog ./public/.frog"
+//   }
+// }
+// ```
+// Next, you'll want to set up the devtools to use the correct assets path:
+// ```ts
+// devtools(app, { assetsPath: '/.frog' })
+// ```
