I needed a way to study a stack of notes I had written for a job interview. Eight markdown files, plus some code examples, plus a couple of reference pages. I wanted to read them in a browser with a sidebar, dark mode, and clickable navigation between files. But I did not want to install a static site generator, run a dev server, or maintain a build pipeline for what is basically a personal study folder. So I built a single-page viewer in one HTML file that reads the markdown directly. The whole site is one index.html plus the markdown files. You open the HTML in a browser, it fetches the markdown, renders it with marked , and you have a real navigable site. This post walks you through the whole pattern. By the end you will be able to drop the same setup into any folder of notes you want to read like a website.…
