Markdown vs HTML — When to Use Which
Quick answer: Use Markdown for docs, READMEs and notes where readability matters more than layout control. Use HTML when you need full styling, embedded media, custom components or precise structure.
Markdown and HTML solve the same problem — turning plain text into formatted documents — from opposite ends. Markdown optimises for the person writing and reading the raw text; HTML optimises for the browser rendering a precise, fully styled result. Knowing which one a task calls for saves a lot of fighting with the wrong tool.

Why Markdown took over documentation
Markdown's whole appeal is that the raw text is already readable. A heading is just a line that starts with #, emphasis is a word wrapped in asterisks, and a link is text in brackets followed by a URL. You can learn the entire syntax in a few minutes, and a Markdown file is perfectly legible even before it's rendered. That's why READMEs, wikis, chat apps and note-taking tools almost all settled on it.
The trade-off is deliberate: Markdown gives you a small, fixed vocabulary of formatting. You can't centre a heading, set a font or build a two-column layout in plain Markdown, because limiting those choices is exactly what keeps it simple.
When you need HTML instead
Reach for HTML the moment you need control Markdown won't give you: custom styling, precise spacing, embedded video, forms, tables with merged cells, or any interactive component. HTML is also the right answer for marketing emails, where rendering quirks across mail clients force you to be very explicit about structure.
A common, productive workflow is to write in Markdown and convert to HTML only at the end, so you get the easy authoring experience and the precise output.
