 For the front-end, we write Svelte components in `src` and generate `bundle.js` and `bundle.css` via `npm run dev` / `npm run build`.
 
 For UI, we make use of TailwindCSS (currently loaded via CDN with some plugins) and Shoelace.Style. Whenever possible, we use Shoelace's existing components.

+## Build

+We use Neutralino.js to generate native apps for Mac/Windows/Linux. Currently only the .app file (not .dmg) for Mac runs correctly.
