- Git is a version control system (VCS) that allows tracking changes to files and coordinating work across multiple people. It is not the same as GitHub, which is a platform for hosting remote Git repositories. - The basic Git commands are git init to create a local repository, git add to stage files for the next commit, git commit to save file changes to the local repository, git clone to copy a remote repository, git pull to retrieve changes from the remote, and git push to upload local changes to the remote. - Git repositories have branches to isolate different lines of development. The default branch is usually called master, but additional branches like testing can be created and merged back in.

● Dirty / modified

12. What is Github then ?
● Remote repositories

13. Git in
6 commands

14. git init
Use the git init command to create a Git repository in the
current directory. Git does not care whether you start with an
empty directory or if it contains already files.

15. git add <file>
Moves files to staging area.
The staging area is the place to store changes in the working tree before the
commit. The staging area contains a snapshot of the changes in the working tree
(changed or new files) relevant to create the next commit and stores their mode
(file type, executable bit).

16. git commit
Creates a commit object in the Git repo.
This commit object uniquely identifies a new revision of the content of the
repository.

17. git clone <url>
Copies an existing repository.
This copying process is typically called cloning and the resulting repository can be
referred to as a clone.

18. git pull
The git pull command allows you to get the latest changes
from another repository for the current branch.

19. git push
The git push command allows you to send data to other
repositories. By default it sends data from your current branch
to the same branch of the remote repository.
By default you can only push to bare repositories (repositories without working
tree).

20. git <everything>
● git status
● git log
● git diff
● git fetch
● git merge
● git blame

21. A tree has
branches

22. A branch in Git is simply a lightweight movable pointer to one
of these commits.
The default branch name in Git is master .
As you start making commits,you’re given a master branch
that points to the last commit you made. Every time you
commit, it moves forward automatically.

23. git branch testing

25. git checkout testing
