# Version Control
We always use source code control. It's like a time machine. We can work in parallel universes of our source code, experimenting without fear of losing work, rolling back if something goes wrong.
Git (opens new window) is an open source source code control system written by Linus Torvalds. It's fast and great for working in branches.
We use GitHub (opens new window) and GitLab (opens new window) for hosting our Git repositories.
