 ## Checklist
 
-- Use [SSG](https://kit.svelte.dev/docs/adapter-static) and/or [SPA](https://kit.svelte.dev/docs/single-page-apps) via `static-adapter`. Tauri doesn't support server-based solutions.
+- Use [SSG](https://kit.svelte.dev/docs/adapter-static) and [SPA](https://svelte.dev/docs/kit/single-page-apps) via `static-adapter`. Tauri doesn't support server-based solutions.
+- If using SSG **with prerendering**, be aware that `load` functions will not have access to tauri APIs during the build process of your app. Using SPA mode (without prerendering) is recommended since the load functions will only run in the webview with access to tauri APIs.
 - Use `build/` as `frontendDist` in `tauri.conf.json`.
