Even if the primary purpose of "git checkout <branch>" is to "check out the branch so that further work is done on that branch", I don't believe that means it has to be stated first. In fact, I would say that there are enough other use cases that the language should be slightly more use-case agnostic in the first situation. For example, someone might switch to another branch or commit simply to see what state the tree was in at that point. Some people use checkout to deploy a tag of the working tree onto a production server. The first example in particular is, I think, a common enough operation that restricting the opening lines of documentation to talking about building further work is misleading. My earlier submission dealt with this by using the 'Switch to the specified ...' terminology. For me this is implicitly stating 'Switch the state of the repository to be the same as the specified ...' but perhaps it would do to be more explicit? I prefer the shorter form myself. By following this with the typical use case it makes it clear what the intended use of the command is, and some idea about the mechanics of its function. I realised that my signature was improperly placed when I submitted my suggestion last, so I will include it here as reference for anyone who skipped over it. It builds on top of the two original patches.

Use this terminology more consistently. Expand on the purpose of switching to a branch or commit, which is typically to prepare to build history on top of that branch or commit.
