Markdown Formatting Guidelines

Below are key Markdown formatting rules with practical examples:

Headings: Use number signs (#) to define heading levels. More #s correspond to lower heading hierarchy.
- Example:
```
# Level 1 Heading
## Level 2 Heading
### Level 3 Heading
```
List Items: Start each item with a dash (-). Indent nested items with spaces or tabs.
- Example:
```
- Primary list item
- Another primary item
  - Nested list item
  - Second nested item
```
Emphasized Text: Wrap text with asterisks (*). Use one pair for italic, two pairs for bold.
- Examples:
```
*Italicized content*
**Bold content**
```
Code/Commands: Use backticks (`) for inline code, or three backticks (```) for multi-line code blocks. Add a language tag after opening backticks for syntax highlighting.
- Examples:
```
`const x = 10;`
```
```
function calculateSum(a, b) {
  return a + b;
}
```
Quoted Text: Prepend lines with a greater-than sign (>). Add more > for nested quotes.
- Example:
```
> This is a quoted paragraph.
>> This line is a nested quote inside the first one.
```
Links: Wrap display text in square brackets ([]), followed by the target URL in parentheses (()).
- Example:
```
[Link Display Text](your-target-url)
```
Images: Add an exclamation mark (!) before square brackets (for alt text), followed by the image URL in parentheses.
- Example:
```
[Image Alt Text](your-image-url)
```
