Track your work with Git

Git is how the world manages code and configuration. Security folks use it to version their scripts, share tools, and review changes, and changes to configuration are often exactly where vulnerabilities sneak in.

Learn the basics:

• Repositories, commits, and history
• Branches and merging
• Pushing to and pulling from GitHub

A bonus: a public GitHub of your scripts and notes becomes part of your portfolio when you job hunt.
