I also started something similar at https://jacobsims.github.io/til/ -- to search them you can just use GitHub search, which is available in that top bar. I also spent a bit more effort creating category pages that look like fancy little tags (due to limits of Jekyll, I can't paginate them, but it will work for a while anyway).

I do plan to reference back to the notes or else they would be meaningless. My current solution is to add categories to the posts and the use jekyll to generate a page where I create a headline for each category and link to all related posts there. This may not be the final solution, it was thrown together one evening so there's improvement.

I don't know how this will scale since I just started this project.

Understandable, thanks for the reply
