Introduction to Markdown

Markdown, created by John Gruber in 2004, is a way to style text on the web. You control the display of the document; formatting words as bold or italic, adding images, and creating lists are just a few of the things we can do with Markdown. Often, Markdown is used to format readme files, for writing messages in online discussion forums, and to create rich text using a plain text editor.

Why use Markdown?

• Simplicity: Markdown is incredibly easy to learn and use.
• Readability: Markdown documents are easy to read, even in their raw form.
• Flexibility: You can use Markdown to create everything from simple notes to complex documents.
• Compatibility: Many platforms and tools support markdown, including Jupyter Notebook, GitHub, and many blogging platforms.

Markdown Basics

Let's start with some basic Markdown syntax. Here are some common elements you might use in a Markdown file:

1. Headers

Headings are used to create titles and subtitles in your document. Use the # symbol, followed by a space, to create headings. The number of # symbols indicates the level of the heading. There are six levels of headers, from H1 to H6.

# This is an H1
## This is an H2
### This is an H3
#### This is an H4
##### This is an H5
###### This is an H6

2. Emphasis

You can emphasize text using asterisks or underscores.

• Bold: **bold text** or __bold text__
• Italic: *italic text* or _italic text_
• Bold and Italic: ***bold and italic text*** or ___bold and italic text___

*This text is italic*
_This text is also italic_
**This text is bold**
__This text is also bold__
_You **can** combine them_

3. Lists

Markdown supports both ordered and unordered lists.

• Unordered Lists: Use asterisks, plus signs, or hyphens followed by a space.

            * Item 1 *
            * Item 2 *

            * Item 3 *

• Ordered Lists: Use numbers followed by a period and a space.

            1. Item 1
            2. Item 2
            3. Item 3

Unordered Lists

- Item 1
- Item 2
  - Subitem 2.1
  - Subitem 2.2
- Item 3

Ordered Lists

1. First item
2. Second item
3. Third item
   1. Subitem 3.1
   2. Subitem 3.2

6. Blockquotes

Blockquotes are used to highlight quotations. Use the > symbol, followed by a space.

> It can span multiple lines.

7. Code

To highlight code, use backticks.

• Inline code: This is inline code``
• Code blocks: Use triple backticks before and after the code block.

Advanced Markdown Features

| Header 1 | Header 2 | Header 3 |
|----------|----------|----------|
| Row 1    | Data 1   | Data 2   |
| Row 2    | Data 3   | Data 4   |
