A Beginner's Guide to Markdown (.md) File Type

21 Jan 2025

Markdown is a lightweight markup language that allows you to format text using a plain-text editor. Files written in Markdown use the .md or .markdown file extension and are widely used for documentation, README files, blog posts, and technical writing.

Why Use Markdown?

• Simplicity: Easy to learn and read.
• Portability: Works with most text editors and version control systems like GitHub.
• Flexibility: Converts to various formats like HTML, PDF, or Word.
• Compatibility: Used in platforms like GitHub, Jekyll, and Hugo for websites and documentation.

Getting Started with Markdown

Basic Syntax

Markdown uses special characters to format text. Here’s a quick overview:

1. Headings
   • Use # symbols to create headings. The number of # determines the heading level.

     markdown
     # Heading 1
     ## Heading 2
     ### Heading 3
     

2. Emphasis
   • Use * or _ for italics and ** or __ for bold.

      markdown
      *Italic* or _Italic_
      **Bold** or __Bold__
     

3. Lists
   • Unordered: Use -, *, or +.

    markdown
    - Item 1
    - Item 2
   

   • Ordered: Use numbers followed by a period.

      markdown
      1. First item
      2. Second item
     

4. Links
   • [Text](URL)

      markdown
      [Visit GitHub](https://github.com)
     

5. Images
   • ![Alt Text](Image URL)

      markdown
      ![Sample Image](https://example.com/image.png)
     

6. Code Blocks
   • Inline code: Use backticks (`).

      markdown
      Inline `code snippet`
     

• Block code: Use triple backticks (```).

    markdown
    def hello_world(): print("Hello, World!")
  

Advanced Markdown Features

1. Blockquotes
   • Use > to create blockquotes.

     markdown
     > This is a blockquote.
     

2. Horizontal Rule
   • Use ---, ***, or ___ for a horizontal line.

     markdown
     ---
     

3. Tables
   • Use | to create tables.

     markdown
     | Column 1 | Column 2 | Column 3 |
     |----------|----------|----------|
     | Row 1    | Value 1  | Value 2  |
     | Row 2    | Value 3  | Value 4  |
     

4. Task Lists
   • Use - [ ] for unchecked tasks and - [x] for checked ones.

    markdown
    - [x] Completed task
    - [ ] Pending task
   

5. Footnotes
   • Use [^1] for footnotes.

    markdown
    Here is a sentence with a footnote.[^1]
   
    [^1]: This is the footnote text.
