Understanding Git - Good references

Git is getting more and more popular these days. Most of the open source project moved to GIT and the ones that didn't yet are in the process of doing it.
Github itself is a great place to share your code and collaborate with other people!

There are a few things you need to get your head around , there are new concepts and "jumping" to the command section without reading the introduction is not always a good idea, you'll have to go back to it.

The one thing that really helped me was this two videos here that I would strongly recommend you to watch.
I am the kind of guy that is suffering to sit at the chair watching a video for 2 hours but if you are struggling with GIT this is worth it.

Also another great resource is think like a git

• gitref,
