It is a topic branch intended for a maintainer to pull into their tree.
It is not a standalone tree which you can just use -- that is why I
described below how to pull it into an existing base.
You will find that the majority of git branches are topic branches which
do not standalone. If you intend to be pulling peoples development
branches then I strongly recommend you google up some git documentation
and learn all about branches and merging etc.
