Git and GitHub

Git keeps a history of your work. Each time you reach a good point you make a commit: a saved snapshot with a short message about what changed. You can always go back.

GitHub is a website that stores Git projects (repositories) online, so you can share them, work with others and show employers what you have built.

git status                 # what has changed?
git add app.py             # choose what to save
git commit -m "Add unit converter"
git push                   # send it to GitHub
