Use Git as a distributed history and collaboration system, not merely a place to upload files. Understand how changes move from the working tree into commits and shared branches.
How this module works
Keep changes small, inspect the diff before recording it, choose the correct history operation, and preserve shared history when other people may already depend on it.
