Introduction to Markdown

Markdown is a lightweight markup language with plain-text formatting syntax. Its main goal is to be readable and easy to write, even when viewed as plain text. Markdown is widely used for creating formatted text on the web and in various applications such as Jupyter Notebook.

Basic Syntax

Headings

Headings are created by adding one or more # symbols before your heading text. The number of # symbols indicates the level of the heading.

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

Emphasis

You can make text bold by wrapping it with two asterisks **, and italic by using one asterisk *.

*italic* or _italic_
**bold** or __bold__

Lists

Unordered lists are created using *, -, or +, while ordered lists are numbered.

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

1. First item
2. Second item

Links

Links are created using [Link Text](URL)

Images

Images are created using ![Alt Text](Image URL).

Advanced Syntax

Blockquote

> Be yourself. Everyone else is already taken. - Oscar Wilde.

Emojis

A ton of markdown emojis are available here 😄 (:smile:)

Code Blocks

Code blocks are created by using triple backticks (```). Optionally, you can specify the language for syntax highlighting.

```
"string"
```

```python
# Python code block
import numpy as np
```
