Frequently Asked Questions

What is Markdown?
Markdown is a lightweight markup language created by John Gruber in 2004. A Markdown (.md) file is plain text with simple formatting syntax — headings (#), bold (**text**), lists (- item), links ([text](url)), code blocks (```), and tables. It's human-readable as plain text and renders to rich HTML. Markdown is the standard for README files, documentation, blogs, and developer content across GitHub, GitLab, and every major platform.
Markdown vs HTML — When to use which?
Markdown is easier to write and read — ideal for documentation, READMEs, blog posts, and any text-heavy content. HTML offers full control over layout and interactivity — needed for web pages, emails, and complex UIs. Most static site generators (Next.js, Hugo, Jekyll) let you write in Markdown and compile to HTML automatically. Use Markdown for content authoring, HTML for presentation.
GitHub Flavored Markdown features — What does GFM add?
GFM extends standard CommonMark with features GitHub developers need: task lists (- [x] done), pipe tables (| col | col |), strikethrough (~~text~~), autolinks (URLs become clickable), and fenced code blocks with syntax highlighting (```js). Our sample-500kb.md and sample-readme.md include all GFM features for testing. Most modern parsers (marked, remark, markdown-it) support GFM.
How do I render Markdown to HTML?
JavaScript: marked.parse(mdText) or remark().process(mdText). Python: markdown.markdown(md_text). CLI: pandoc input.md -o output.html. Online: GitHub renders .md files automatically. Static site generators (Next.js, Hugo, Jekyll, Docusaurus) process Markdown as part of their build pipeline.
What is a README.md file?
README.md is the standard documentation file for software projects on GitHub, GitLab, and npm. It typically contains: project description, installation instructions, usage examples, API reference, and contributing guidelines. Our sample-readme.md provides a realistic template with badges, code blocks, tables, and proper heading hierarchy — download it to test README rendering.
