I'm a free-lance web developer (working alone) and I've got tired of working with different versions of my files with slightly different names. I always get confused in the end. So I'm having a real try to adopt a version control system. I understand the broad principles of Git, but I thought it would be easier to use the Sourcetree GUI.
But I can't find a manual. I can get specific questions answered, but I was hoping to find some documentation that would take me through the process from the beginning, with particular reference to converting existing projects (with no formal version control) to Git.
Can you suggest a source, please ? I'd even buy a book if it exists.
