Learn Enough Git to Be Dangerous
I linked to the free online version because that feels like the more HN thing to do, but there's also an announcement post that includes a 15% launch discount on ebook sales:<p><a href="http://news.railstutorial.org/learn-enough-git-ebooks/" rel="nofollow">http://news.railstutorial.org/learn-enough-git-ebooks/</a><p>I'll plan to be around for a bit this afternoon in case anyone has any questions. I've already gotten a lot of great feedback on <i>Learn Enough™ Git to Be Dangerous</i>, so thanks for all the support!
