What is Git?

Git is a distributed version-control system for tracking changes in any set of files, originally designed for coordinating work among programmers cooperating on source code during software development. Its goals include speed, data integrity, and support for distributed, non-linear workflows.

Installing Git

Install git by visiting https://git-scm.com/downloads and install the appropriate binary for your OS.

Common Git Commands

1. git init to create a new repository in a directory
2. git add to track files for changes
3. git commit commits those changes permanently in version control history
4. git push to push your work to a remote Git host
5. git log to see commit history
6. git remote to see what remotes is your repo connected to
7. git branch to create a new branch
8. git checkout to switch to another branch
   1. Tip: use git checkout -b to create a new branch and switch to it
9. git stash to remove all local changes in working directory since the last commit

.gitignore

All files and folders you add to the .gitignore file will not be checked into version control.
