+## License
 
-```sh
+MIT
-# recreate this project
-pnpm dlx sv@0.15.3 create --template minimal --types ts --add prettier eslint tailwindcss="plugins:none" sveltekit-adapter="adapter:static" mcp="ide:claude-code+setup:local" --install pnpm .

-
-## Developing
-
-Once you've created a project and installed dependencies with `npm install` (or `pnpm install` or `yarn`), start a development server:
-
-```sh
-npm run dev
-
-# or start the server and open the app in a new browser tab
-npm run dev -- --open
-```
-
-## Building
-
-To create a production version of your app:
-
-```sh
-npm run build
-```
-
-You can preview the production build with `npm run preview`.
-
-> To deploy your app, you may need to install an [adapter](https://svelte.dev/docs/kit/adapters) for your target environment.
