This is a post I will be adding to over time all about links I have found useful when learning how to best use Git.
Latest Edited: 02/11/17
Git Immersion - One of the better beginner tutorials to Git I have looked through, it covers all the basics.
A successful Git branching Model - The title says it all really, a really nice way method for branching during the product life-cycle.
Git - The Simple Guide - Really nice beginners guide to Git.
How To Create And Apply A Patch - Really good article, the only thing I would clarify is that the am command can only be used once you have set up mailing (something I have yet to do).
Creating A New Branch On Your Remote Repository - Such a simple task but one I couldn't easily find described somewhere for the layman.
Branching and Merging - An interesting document on branching and merging within Git.
Thanks to @psynnott for contributing some links.
