Markdown has become the default format for developer documentation, READMEs, and CMS content. But browsers render HTML — so a conversion step is always needed.
Why Markdown?
Markdown is faster to write, easier to read as plain text, and cleaner in version control diffs than HTML. Most documentation platforms (GitHub, Notion, GitBook) store content as Markdown and render it server-side.
The conversion basics
A Markdown processor walks the source text and maps constructs to HTML elements: # Heading → <h1>, **bold** → <strong>, [text](url) → <a>, and so on.
Things that don't survive conversion cleanly
- Raw HTML inside Markdown — most processors pass it through, but sanitizers may strip it in security-conscious contexts.
- Flavour differences — GitHub-Flavoured Markdown (GFM) supports tables and task lists; CommonMark doesn't.
- Indentation-sensitive blocks — nested lists require exactly 4 spaces or 1 tab in some processors.
Best practice for content pipelines
Convert at build time, not at runtime. Pre-converting Markdown to HTML means zero parsing overhead for users and lets you sanitize the output once.
