Verifying Markdown Formatting

Check a Markdown file for formatting issues and fix them.

What to Check

Structure

• Exactly one # H1 heading at the top of the file
• Headings increment by one level (no jumping from ## to ####)
• Blank line before and after every heading
• Blank line before and after every code block, list, and blockquote
• File ends with a single trailing newline

Lists
