+# Welcome to Remix + Vite!
+
+📖 See the [Remix docs](https://remix.run/docs) and the [Remix Vite docs](https://remix.run/docs/en/main/guides/vite) for details on supported features.
+
+## Typegen
+
+Generate types for your Cloudflare bindings in `wrangler.toml`:
+
+```sh
+pnpm typegen
+```
+
+You will need to rerun typegen whenever you make changes to `wrangler.toml`.
+
+## Development
+
+Run the Vite dev server:
+
+```sh
+npm run dev
+```
+
+To run Wrangler:
+
+```sh
+npm run build
+npm start
+```
+
+## Deployment
+
+If you don't already have an account, then [create a cloudflare account here](https://dash.cloudflare.com/sign-up) and after verifying your email address with Cloudflare, go to your dashboard and set up your free custom Cloudflare Workers subdomain.
+
+Once that's done, you should be able to deploy your app:
+
+```sh
+pnpm run deploy
+```
