Basic Knowledge
What is Markdown?
Markdown is a notation that represents document structure using simple symbols like "# Heading" and "**bold**". It is commonly used across a wide range of services including GitHub README files, chat tools, and blogs.
Common Syntax
- Headings：Adding # at the beginning of a line creates a heading. Adding more # symbols (like ##) creates lower-level headings.
- Emphasis：Wrapping text in **two asterisks** makes it bold, and wrapping it in *one asterisk* makes it italic (emphasis).
- Lists：Adding "- " at the beginning of a line creates a bulleted list, and using numbers like "1. " creates a numbered list.
