Maren is a theme based markdown renderer. It is suitable to create a simple site or a blog such as this one, pavelbucka.com. Check Maren at https://maren.io.
This blog, pavelbucka.com, is created using Maren.
Below are two more examples that showcase Markdown elements and are inspired by Markdown Guide. The two examples look almost identical by the content, whereas the second example comes with one extra, a generated TOC (table of contents) that is shown in the top of the page (depends on the used theme/template).
