What repo to start with ?

Under this link- https://github.com/bluesky-social

There are lot of repos. There is an example stratusphere repo. However, if I need to start and fork one of the repos to build my own private bskySocial kind of social network, that is invite only. Which repo do I start with ?
As a starting point - if I can run it locally and open the webpage locally that will be great.

thank you !!
