Making changes in the working directory There are 2 types of files in the working directory: Tracked: files that Git knows about. Untracked: files that have still not been added, so Git doesn’t know about.

Updating the remote repository As changes are ready in the working directory, they must be added in the staging area. When there is a set of changes with a single purpose in the staging area, it’s the time to create a commit with a message about that purpose in the local repository. When there are one or several commits in the local repository ready to be shared with the rest of the world, they must be pushed to the remote repository.
