Markdown Formatting Rules & Examples

Below are the key Markdown formatting guidelines you requested, each paired with a clear example to show exactly how to use them:

Headings: Use number signs (#) at the start of a line. The more #s you use, the smaller the heading level (from 1 to 6):
- # Level 1 Heading → # Level 1 Heading
- ### Level 3 Heading → ### Level 3 Heading
List Items: Start each list entry with a dash (-). You can create nested lists by indenting the sub-items:
- First list item
  - Nested sub-item
  - Another nested sub-item
Emphasized Text: Wrap text with single asterisks (*) for italic styling, or double asterisks (**) for bold:
- *This text is italicized* → This text is italicized
- **This text is bolded** → This text is bolded
Code/Commands: Surround inline code snippets with backticks (`). For multi-line code blocks, use three backticks (```) at the start and end of the block:
- Inline code example: npm install package-name
- Multi-line code block example:
```
def calculate_sum(numbers):
    total = 0
    for num in numbers:
        total += num
    return total
```
Quoted Text: Prefix each line of the quote with a greater-than sign (>):
This is a blockquote example.
You can extend it across multiple lines by adding > to each new line.
Links: Wrap the text you want to display in square brackets ([]), then follow it with the target URL in parentheses (()):
- [Your Link Text](https://your-target-url.com) → Your Link Text
Images: Start with an exclamation mark (!), then add alt text in square brackets ([]), followed by the image URL in parentheses (()):
- ![Image Description](https://your-image-url.com) →
