So I did my first commit to my GitHub for this theme. I need to read about the licensing regarding Semantic-UI's work and make sure they are properly credited. Either way, I'm glad the initial commit/push is done. I doubt any other PicoCMS user will use this theme beside myself, but it's available now for anybody to clone and start using.
I don't know how active I'll be developing this further, but I'll slowly work on this to my fit my needs, and continue to learn more about front end design work while doing so. I really enjoy learning more about PicoCMS, Twig and Semantic-UI so far, and I feel that the more I learn regarding these things, the more it helps out with my professional life.
