About Markdown Previewer
Markdown is a lightweight markup language created by John Gruber in 2004 for writing formatted text using plain text syntax. It converts to HTML automatically. Core syntax: hash symbols for headings (one hash for H1, two for H2); asterisks for bold and italic; hyphens or asterisks for unordered lists; numbers for ordered lists; backticks for inline code; triple backticks for code blocks; square brackets followed by parentheses for links; exclamation mark added for images.
Markdown is used on GitHub (README files, issues, pull requests), Stack Overflow, Reddit, Slack, Discord, Notion, Confluence, and most modern documentation platforms. GitHub Flavoured Markdown (GFM) adds tables, strikethrough, task lists with checkboxes, and syntax highlighting for code blocks. Knowing markdown is a practical skill for any developer or technical writer - it is faster than HTML for writing structured content and renders consistently across platforms.
