Introduction to Git

What is Git?

Git is a distributed version control system.
It allows you to track file history, collaborate with others, and roll back to a previous state in case of error.

➡ Unlike a simple backup, Git records each modification with a commit.

Git vs GitHub

• Git = the tool installed locally, used to manage your repositories.
• GitHub/GitLab/Bitbucket = online platforms to host and collaborate on repositories.

Quick example

git init             # create a Git repository
git add .            # add all files
git commit -m "Init" # commit the files

Best practices

• Always write clear commit messages.
• Don’t confuse Git (tool) with GitHub (platform).
• Remember to use .gitignore to exclude unnecessary files.
