The indispensable xkcd about git
Abstract:
Starting out as a week-long project by the inventor of Linux, git has become the de facto standard when it comes to version control of text files and in particular source code – such as .tex-files. In this talk I will explain, how git works and why it is helpful for mathematical writing. In particular, we will address how git allows to keep track of big projects, like theses or books, and work collaboratively on papers and the like. Plus, git can be explained through graph theory!
The slides of this talk are available here and the source code is in this git repository.
