 Supabase client for Python. This mirrors the design of [supabase-js](https://github.com/supabase/supabase-js/blob/master/README.md)
 
+## Status
+- [x] Alpha: We are testing Supabase with a closed set of customers
+- [x] Public Alpha: Anyone can sign up over at [app.supabase.io](https://app.supabase.io). But go easy on us, there are a few kinks.
+- [ ] Public Beta: Stable enough for most non-enterprise use-cases
+- [ ] Public: Production-ready
+
+We are currently in Public Alpha. Watch "releases" of this repo to get notified of major updates.

 ### Running Tests
 
 Currently the test suites are in a state of flux. We are expanding our clients tests to ensure things are working, and for now can connect to this test instance, that is populated with the following table:
