This repo is the source files for the website https://mmdc-net.github.io
This project uses the Hexo framework.
The way I am using it, I have two repos, one for source files and one for the destination files. The latter is not edited directly, only modified from this repo.
Hexo uses Markdown for editing the pages it serves. (They get converted to html when they are generated and deployed.) Have a look at the files in source/_posts to see the Markdown files.
