I don't understand how git works. Have tried it some time ago, but 
didn't work, so I gave up. No good instructions available. A second 
computer with Linux seems to be required. Too complicated. I have no 
experience with Linux. I know C and C# programming, but I'm not a 
professional programmer. The page https://www.ffmpeg.org/git-howto.html  
was obviously not written for beginners. Many terms are introduced 
without explaining them, and examples are missing.
