Markdown Formatting Quick Guide

Here's a simple, easy-to-follow rundown of key Markdown formatting rules you can use:

Headings: Use number signs (#) to define headings. The number of # corresponds to the heading level (1 being the largest, 6 the smallest):
```
# Level 1 Heading
### Level 3 Heading
```
Unordered List Items: Start each list entry with a dash (-). For nested lists, just indent the sub-items:
```
- First list item
- Second list item
  - Nested sub-item
```
Text Emphasis: Wrap text with single asterisks (*) for italicization, or double asterisks (**) for bold:
```
*This is italic text*
**This is bold text**
```
Code & Commands: Use single backticks (`) for inline code snippets, and three backticks (```) for multi-line code blocks (you can add a language tag for syntax highlighting):
```
Inline code example: `npm start`
Multi-line code block:
```javascript
function greet(name) {
  return `Hello, ${name}!`;
}
```
Quoted Text: Prefix any text with a greater-than sign (>) to create a blockquote. Stack multiple > for nested quotes:
```
> This is a standard blockquote
>> This is a nested quote inside the first one
```
Links: Format links as [Visible Link Text](Target URL) — readers click the visible text to navigate to the URL:
```
[Markdown Basics](https://example.com/markdown-basics)
```
Images: Use [Alt Text](Image URL) where alt text describes the image (for accessibility or when the image can't load):
```
[Sunset Over Mountains](https://example.com/sunset.jpg)
```
