+# My personal website
+
+This is source code for [knazarov.com](https://knazarov.com), my personal website.
+It is written mostly in bash, and uses [markdown.awk](https://git.sr.ht/~knazarov/markdown.awk) to convert
+markdown posts and pages to HTML.
+
+The site has very minimal CSS (about 110 lines) that should be enough to display fine in most browsers
+including mobile.
+
+I don't intend the code to be easily readable, but given that it's not much, you can probably figure
+things out.
+
+## Building
+
+If you're on any Linux system, you can just type `make` in your terminal, and the result will be in the
+`./output` directory. However, if you're on a Mac, you probably would need to use gnu awk/sed.
