What is Markdown Previewer?
Markdown is a lightweight markup language that uses plain-text formatting syntax. It was created by John Gruber in 2004 as a way to write for the web without needing HTML tags. For example, **bold** becomes <strong>bold</strong>, and # Heading becomes an <h1> tag. Markdown is used in GitHub READMEs, documentation, blog posts, and note-taking apps.
