codecrafters-io/build-your-own-x ? reverse-engineered prompt

I want to build a website that's a nice front-end for the popular "build-your-own-x" GitHub repository. That repo is an awesome list of tutorials for recreating technologies from scratch, but it's just a big markdown file. I'd like to create a clean, modern, and browsable web interface for it.

The site should automatically pull in all the categories from the repo, like "Build your own Database," "Build your own Game," etc. When a user clicks a category, they should see all the linked tutorials. Please also display the programming language for each tutorial, just like in the original file. A key feature would be a search or filter bar so users can easily find all projects for a specific language, like Python or Go. The design should be simple, professional, and focused on making this amazing resource easier to explore.
