Best Practices - UNGPhysics/welcome GitHub Wiki

Avoid creating similar copies of the same thing. For example, it is a bad practice to have a bunch of repositories like phys2212-harrison-spring2018, phys2212-harrison-fall2018, phys2212-harrison-spring2019, etc. Rather, have a single repository called phys2212-harrison that evolves with time. Git will preserve the repository's history and you can use tools like Tags, Branches, and Forks to help you stay organized.

Avoid putting binary files (especially large ones) in repositories when possible. For example, a LaTeX source is much better than a Word document or a pdf file. Images to be used in a document are generally unavoidable and are okay (but the resolution should be reasonable).
