About the formats

What is EPUB?

EPUB is an open standard format for ebooks, based on XHTML and designed so text reflows to fit any screen. It is supported by most ebook readers, tablets and phones, and is the format you find in most online bookstores. Because the text adapts to the device, reading stays comfortable on small and large screens alike.

Use EPUB when you publish an ebook or a long document meant to be read on e-readers, tablets or phones. Its reflowable text makes it the right choice when readers should be able to adjust font size and screen.

What is Markdown?

Markdown is a lightweight markup language that lets you write formatted documents in plain text using simple symbols. The same file reads clearly as text and renders as styled HTML, making it popular for documentation, README files and notes. It is also widely used to feed clean text to large language models.

Use Markdown for content that should be readable as plain text but publishable with formatting, README files, documentation, wikis, notes and posts. Write it anywhere, and it stays usable forever because the source is plain text.
