What is Markdown?
Markdown is a lightweight markup language created by John Gruber in 2004. It was designed to be easy to read and write as plain text while converting seamlessly to structurally valid HTML. Unlike raw HTML, Markdown uses simple punctuation characters — such as hashes, asterisks, and dashes — to indicate headings, bold text, lists, and more.
Today, Markdown is widely adopted across the software industry. Platforms like GitHub, GitLab, and Stack Overflow use it as their primary content format. It is the standard for README files, project documentation, technical wikis, and blog posts. Because it converts directly to HTML, Markdown is far simpler for content writing while remaining powerful enough for complex documents.

Frequently Asked Questions
What is GitHub Flavored Markdown?
GitHub Flavored Markdown (GFM) is a superset of standard Markdown maintained by GitHub. It adds task lists with checkboxes, pipe tables, strikethrough text, autolinked URLs, and fenced code blocks with language-specific syntax highlighting.
Can I export markdown to PDF?
Yes. Click the export button and choose PDF. The editor renders your Markdown to a clean, print-ready PDF that preserves headings, code blocks, images, and tables — ideal for sharing reports or documentation offline.
Does this editor support code syntax highlighting?
Absolutely. Fenced code blocks with a language identifier (for example, ```javascript) are automatically highlighted for dozens of languages including JavaScript, Python, TypeScript, Go, Rust, and many more.
What is the difference between Markdown and HTML?
HTML is a full markup language with opening and closing tags (e.g., <h1>). Markdown uses minimal punctuation (e.g., #) to represent the same structures. Markdown is faster to write and easier to read as plain text, but it converts to HTML under the hood.
Can I use Markdown for technical documentation?
Markdown is the de facto standard for technical documentation. Tools like MkDocs, Docusaurus, and GitBook all use Markdown as their source format. With support for code blocks, tables, and cross-references, it covers virtually every documentation need.
