This is a thorough introduction of Git I made at the local .Net user group, with special attention to the new Git integration in Visual Studio 2013. You can read more about the preparations I made in this blog-post.
The presentation/video is aimed at Windows/Visual Studio developers that are completely new to Git.
If you are a more experienced used, have a look at the TOC in the YouTube description and skip to the interesting bits if you are looking for something specific. You can also play it back at 1.5x or 2x speed.
