Git is a tool for tracking changes made to a set of files over time,
a task traditionally known as “version control.” Although it is
most often used by programmers to coordinate changes to software
source code, and it is especially good at that, you can use
Git to track any kind of content at all. Any body of related files
evolving over time, which we’ll call a “project,” is a candidate for
using Git. With Git, you can:
• Examine the state of your project at earlier points in time
• Show the differences among various states of the project
• Split the project development into multiple independent
lines, called “branches,” which can evolve separately
• Periodically recombine branches in a process called “merging,”
reconciling the changes made in two or more branches
• Allow many people to work on a project simultaneously,
sharing and combining their work as needed
