+## Markdown
+
+The website uses basic markdown that allows GFM style tables and also supports *some* placeholders:
+
+- `<!-- TOC -->` will insert a table of contents if alone in a single line. The ToC will be rendered in the same depth as the next heading, so everything higher in the hierarchy will be ignored.
+- `<!-- ARTICLES -->` renders a list of all available articles
+- `<!-- ARTICLES10 -->` renders a list of the 10 latest articles
