Githug is an interactive text-based game (or a series of challenges, if ‘game’ isn’t the word), that helps you learn git. It has a series of levels, each of which requires the knowledge of some git commands to solve. Two more levels were added today on checking out tags and solving merge conflicts. You can install the latest version with,
gem install githug
It’ll work on any operating system, given ruby gems is installed. Currently githug consists of 41 levels of increasing difficulty, and more will be added soon.
