 ## Javadocs
 
-When Robolectric is released, the `source/javadocs` directory needs to be updated. This can be done by grabbing the javadocs that were pushed to [Maven Central](http://search.maven.org/#search%7Cgav%7C1%7Cg%3A%22org.robolectric%22%20AND%20a%3A%22robolectric%22) and unjarring them into that directory.

-## Gory Details: How These Docs Get Published
-
-This repository has 2 branches: `source` and `master`. The former is a middleman project that can generate the latter. With every commit that is made to the `source` branch, Travis CI runs middleman and deploys the results back to the `master` branch. It does this by using an OAUTH token belonging to the robolectric-travis-bot user, who only has permission to commit and push to this repository.
