Getting Started with Git
For those of you that are completely new to Git (and maybe version control altogether) we've created "learn-git.com". The content is aimed at beginners of version control and covers all the basic topics. An eBook with a free online version as well as a complete video course help you get started as easily as possible.
If you're coming from Subversion, we have a helpful overview for you: Switching from Subversion to Git explains the most important differences between the two systems.
Tip: We strongly recommend learning at least the basics of both Git and version control. Only when understanding the basic concepts and commands will you be able to use Tower (and version control) effectively.
