a. There could be a section on branching separate from “Working with Others in GitHub/GitLab”
b. In the section on working with others/documenting could include selection and posting of a license. Even if just to say “follow your agencies policies” but “a license should always be present with any public repository”.

We will add a chapter before chapter 8 on branching locally, and add content in chapter 11 about working with branches remotely
