My git journey
Sometimes I feel lucky that the first company I worked for as a software developer was using Subversion instead of SourceSafe. As I remember it, Subversion together with the Windows Explorer integrated Subversion client TortoiseSvn, was pretty easy to learn and felt as a great tool. Sure, there were some gotchas, but still, the learning curve felt pretty flat.
When I moved on, from employment to employment, the companies I came to often used SourceSafe. I could cope with that, because I used Subversion on the side. After many years as a Subversion user, I heard about the greatness of git and tried a few times to get a grip on it... but didn't get it. One of the reasons to that was that as a TortoiseSvn user I thought that TortoiseGit would be almost the same experience. The image below is what you meet when trying to get the source code to your computer, lots of checkboxes I didn't have a clue what they did!
I gave up rather fast, but tried again, and gave up, and so on.
Finally I found the git visual client SourceTree, that was powerful enough to let me do most of the things I needed. Some visual clients was so stripped that it wasn't possible to do anything but the simplest commands. With SourceTree I could finally work with git and began to learn, but the learning curve felt steep, and the fact that I came from Subversion probably made it steeper than if I hadn't had the Subversion thinking. Anyway, now I learned things, but still many things felt really confusing.
Learn Git Branching
One day, I found the site http://learngitbranching.js.org/ Spending some time on that site made a big difference! Suddenly I got a feel for the differences between Subversion and git branches! The two top reasons I find the site so great is that you solve problems using real git commands and that it shows visually what happens with the commits and branches.
Learning git on my own, using SourceTree and the "Learn Git Branching" site, made it possible for me, on my latest employment, to do the migration of the source code from TFVC to git, set up a branching strategy, and to help my collegues get a quick start with git so they didn't have to take the same long journey as me =)
