## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.
YES
## What kind of change does this PR introduce?
Feature, docs.
Part 2 of 6 in a stack that splits the library redesign into reviewable
pieces.
## What is the current behavior?
The library documents individual blocks. Nothing answers "I have no
project yet" — a reader who wants a working app has to assemble one from
block guides and figure out the scaffolding themselves.
## What is the new behavior?
Four starter guides under `/docs/starters`, each starting from an empty
directory and ending with a running app on Supabase:
- **Next.js starter** — composes the library's own password-based auth
block.
- **SaaS starter** — the community subscription-payments template, with
Stripe setup.
- **AI chat app** — the community Vercel AI SDK template.
- **Flutter starter** — the user-management example, with profiles and
avatar uploads.
They reuse the existing doc route, so the sidebar, command menu,
Markdown export and `llms.txt` pick them up with no new plumbing. The
framework selector already renders nothing for pages that declare no
framework variants, so a starter page shows none.
## Additional context
The starter pages are added here in the current site's page layout; the
last PR in the stack converts them to the new one along with every other
guide.
