 ### ⚠️ BREAKING CHANGES
 
-- **new API endpoint path**: ~~`/api/toot`~~ → `/api/share`
-- **new API endpoint port**: ~~`:8000`~~ → `:8080`
-- API endpoint **is now ESM-based** instead of CommonJS
-- **new static path**: ~~`./public`~~ → `./dist`
+Share₂Fedi is now an [Astro](https://astro.build/) site. The migration allowed
+us to have a performant service that is easily hostable on both serverless
+platforms, like Vercel or Netlify, as well as locally. Setting the project up
+now takes seconds! This comes with changes, though:
+
+- **static files aren't built any more**, but generated server-side
+- **new output directory**: ~~`public`~~ → `dist`
+  - this also means that `public` **is not ignored any more**
+
+Some changes came with the name change:
+
+- **changed API endpoint path**: ~~`/api/toot`~~ → `/api/share`
