# Git Git is, by ***far***, the most powerful tool in a programmer's arsenal. It is a command line tool that allows you to do a lot of things with your code, including but not limited to: * Track changes to code * Allow you to work on certain parts of the code without impacting known good code or messing with other people's work * Revert changes to code in case something breaks * Automatically merge different sets of changes so that you (mostly) don't have to do it yourself This chapter will get you started on the basics of Git. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
