Got it, here's a straightforward cheat sheet for the Markdown formatting rules you specified, complete with examples to make implementation easy:

Headings #

Use number signs (#) to denote headings—more signs mean smaller heading levels:

• # Level 1 Heading → # Level 1 Heading
• ## Level 2 Heading → ## Level 2 Heading
• ### Level 3 Heading → ### Level 3 Heading

List Items #

Start each list entry with a dash (-). For nested lists, indent the child items to create hierarchy:

• First main list item
  • Nested sub-item
  • Another nested sub-item
• Second main list item

Emphasized Text #

Wrap text with single asterisks (*) to add italicized emphasis:

• *This text is emphasized* → This text is emphasized

Code/Commands #

Surround code snippets or terminal commands with backticks (`) to format them as inline code:

• To initialize a repo, run git init`` → To initialize a repo, run git init

Quoted Text #

Use a greater-than sign (>) before text to create blockquotes:

• > This is a quoted block of text →

This is a quoted block of text

Links #

Format links by wrapping the display text in square brackets ([]), followed by the target URL in parentheses (()):

• [View Project Documentation](https://example.com/docs) → View Project Documentation
  (Note: Replace the placeholder URL with your actual target link)

Images #

For images, wrap descriptive alt text in square brackets ([]), then add the image's URL in parentheses (()):

• [Profile Avatar](https://example.com/avatar.png) → Profile Avatar
  (Note: Replace the placeholder URL with your actual image link)
