Git is About Communication
An SCM such as Git is more than just a database for source code. It’s not only the thing you need to interact with to get code to production, but also a log of changes on a project. It’s not just the last couple of weeks of commits that are worth looking at. Any commit remains relevant weeks, months and years later. A commit serves multiple purposes. The first one is to explain a change during its review and the second is to explain a change to a future reader.
