I went to look at your dotfiles on your GitHub page https://github.com/flipsidecreations/ and it is showing a 404 not found. I got there from your YouTube description link.
Then I looked at my fork of your dotfiles and realized your GitHub page is now lawrencesystems (Lawrence Systems) · GitHub
So you might want to update your YouTube link for GitHub in the description of your videos?
Thanks for all you do for the community!
