B4 end-user documentation

B4 is a tool created to make it easier for project developers and maintainers to use a distributed development workflow that relies on patches and distribution lists for code contributions and review.

This documentation is split into two main areas – one aimed at maintainers who primarily receive, review, and apply patches to their trees, and the other at developers who submit patches or patch series for maintainer review.
