-The output folder is configuration with the `dist` property when creating the adapter.
-
-```js
-import { defineConfig } from 'astro/config';
-import netlify from '@astrojs/netlify/functions';
-
-export default defineConfig({
-  adapter: netlify({
-    dist: new URL('./dist/', import.meta.url)
-  })
-});
-```
-
-And then point to the dist in your `netlify.toml`:
-
-```toml
-[functions]
-  directory = "dist/functions"
