Sample Markdown files for testing parsers — free, CC0

Markdown is plain text with lightweight formatting, and every renderer treats its corners a little differently. md/readme-style.md is a README-shaped Markdown document of exactly 4,096 bytes, the kind of file every source repository has at its root.

The exact size is useful on its own. 4,096 bytes is a common buffer and memory page size, so the file lands exactly on a boundary that exposes off-by-one mistakes in code that reads text in fixed chunks. Its content makes it a realistic input for renderers, syntax highlighters and documentation tools.

Use it to test Markdown rendering in editors and previews, static site generators, search indexers, and upload forms that accept .md files. It is UTF-8 with LF line endings and is served as text/markdown, so it also checks how a client handles that MIME type when it does not recognise it. Related formats: text files.
