Yes. I was able to set up the repository. I had difficulty, as the screen was so much different. I also did not get from the Lecture that the folder is the actual working directory, rather than a backup folder with copies of the Blender files. When I started Lecture 172 I did not see how SourceTree would know that files are changed. I watched the Lecture again to look at the folder that you saved the file and now I changed the “working” directory to the “repository” folder.
I am old school, I used to do all this manually. I had a working folder and a backup folder and copied the files. I also used to write programs with a text editor like Notepad and compile by typing in the command at the DOS prompt.
Oops. I just revealed that I am an old fart. LOL
