What is Version Control	Version control is like an unlimited ‘undo’. Version control also allows many people to work in parallel.
Setting Up	Use `git config` with the `--global` option to configure a user name, email address, editor, and other preferences once per machine. GitHub needs an SSH key to allow access
Using a Repository	`git clone` creates a local copy of a repository from a URL. Git stores all of its repository data in the `.git` directory.
Tracking Changes	`git status` shows the status of a repository. Files can be stored in a project’s working directory (which users see), the staging area (where the next commit is being built up) and the local repository (where commits are permanently recorded). `git add` puts files in the staging area. `git commit` saves the staged content as a new commit in the local repository. Write commit messages that accurately describe your changes. `git log --decorate` lists the commits made to the local repository, along with whether or not they are up-to-date with any remote repository.
Exploring History	`git diff` displays differences between commits. `git checkout` recovers old versions of files.
Remote Repositories	Git can easily synchronise your local repository with a remote one GitHub needs an SSH key to allow access
Branching	Branches are parallel versions of a repository You can easily switch between branches, and merge their changes Branches help with code sharing and collaboration
