I do something similar to my blog, I even wrote an article about it (that is out-of-date, but the idea is the same): https://kokada.capivaras.dev/blog/using-github-as-a-bad-blog....

Basically I write the posts in Markdown, commit them to the repository and it automatically generates a RSS feed and a index in the repository (inside the README.md file), and also publishes the blog posts to https://kokada.capivaras.dev/, that is where the blog actually lives.
