Thank you nkallen.
On Windows 10, got git installed, and did the first two steps done, the git clone... and git checkout...
Hung up on git commands.patch.

Very slow internet here. Cannot watch video until tonight.

Will try again tonight with fast internet, and watching video.

My file explorer directory structure was temporarily messed up, I guess from git am --directory commands...
>>>After a reboot, the directory structure is back to normal. I'll have to follow the video directions for Windows 10.
