Markdown is a lightweight markup language that's perfect for writing blog posts. Here's a comprehensive guide to using Markdown effectively.

# H1 Header
## H2 Header
### H3 Header

• Bold text with **bold**
• Italic text with *italic*
• Strikethrough with ~~strikethrough~~

Unordered lists:

• Item 1
• Item 2
  • Nested item
  • Another nested item

Ordered lists:

1. First item
2. Second item
3. Third item

• Link text
• 

Inline code: const variable = "value"

Block code:

function greet(name) {
  return `Hello, ${name}!`;
}

This is a blockquote. It can span multiple lines and is great for highlighting important information or quotes from other sources.

1. Keep it simple - Markdown's strength is its simplicity
2. Use headers wisely - Create a clear hierarchy
3. Break up text - Use lists and short paragraphs
4. Add code examples - Show, don't just tell
5. Preview your work - Always check how it renders

Markdown makes writing for the web enjoyable and efficient. Master these basics, and you'll be creating great content in no time!
