Hands-on experience & tips
Markdown keeps the focus on content, not formatting. Its plain-text syntax is easy to read, easy to write and converts flawlessly to HTML, PDF or raw .md files. Platforms like GitHub render it beautifully, which is why README files are almost always written in Markdown.
When you step outside those platforms you still need a local editor. Some devs reach for VS Code, but Mark Text offers a distraction-free, WYSIWYG experience: type # Heading
and you see a real heading, not raw markup. Add a flowchart or equation with a few keystrokes, pick one of six bundled light/dark themes, and you get a publication-ready document without ever touching the mouse.
