Watch all of these videos to understand some of the concepts we'll be going over in the session.
- Git Branches Part 1 by Nathan Kuik (ignore the exercise he mentions :) );
- Git Branches Part 2 by Nathan Kuik;
- Git reset, revert, and cherry-pick, or in short: how to get rid of commits when you mess up, by Ida Naderian;
- Git stash;
- How to solve merge conflicts.
Prepare some questions or confusions you have around git and GitHub and bring them to the session. Think about times you've been stuck, had conflicts, or maybe questions about how to best separate your code into small commits or even how to review a PR.
