What is Markdown?
Markdown is a lightweight markup language designed to be easy to read and write, while still being powerful enough to create rich, formatted documents. It was created by John Gruber in 2004 and has become the standard for writing documentation, README files, and content for the web.
The beauty of Markdown is its simplicity - you can write content using plain text with simple formatting syntax, and then convert it to HTML, PDF, or other formats. It's widely used on platforms like GitHub, GitLab, Reddit, and many content management systems.

Use # symbols to create headers. The number of # symbols determines the header level.

Text Formatting
Use asterisks and underscores for bold and italic text formatting.
**bold**, *italic*, ***bold italic***
Lists
Create unordered lists with - or *, and ordered lists with numbers.
- Item 1, 1. First item
Code
Use backticks for inline code and triple backticks for code blocks.
