When I first viewed the README for this repo, I completely missed the preview of all themes on the wiki. I figured it might help to make the size of the line that directs readers to the wiki to preview the themes a bit larger, which is what I did.
Since this is different from operating system to operating system it's worth calling out here. I spent about a few minutes scratching my head trying to figure out why I was getting theme not found errors. I assumed the Themes directory was the same on MacOS as it is on Linux.
