25.1 What is git?

• git is a version control system.

• Assists developers* when collaborating on big projects.

  • *Data scientists and analysts have adapted it for their needs.

• Manages the set of files (i.e., a repository (or repo for short)) in a structured way.

• Two ways to think about git:

  • It takes snapshots, catalogs, and assists in the documentation of changes to your files.

  • It is like Microsoft Word’s “Track Changes” on steroids.
