FAQ
Markdown syntax questions
What is a Markdown cheat sheet?
A Markdown cheat sheet is a quick syntax reference for formatting headings, links, lists, tables, code blocks, images, quotes, and GitHub-specific Markdown patterns.
Does this include GitHub-flavored Markdown?
Yes. The cheat sheet includes GitHub-friendly patterns such as tables, task lists, issue references, mentions, diff blocks, and collapsible details sections.
How do I make a Markdown table?
Use pipes for columns and a separator row under the header. Add colons in the separator row to align columns left, center, or right.
Can I copy the Markdown examples?
Yes. Each syntax card has a copy button, and the full Markdown reference can be downloaded as a `.md` file.
Is Markdown the same everywhere?
Core syntax is broadly portable, but features like task lists, tables, mentions, and collapsible sections depend on the Markdown renderer. GitHub supports the examples shown here.
