Markdown Syntax Guide
What is Markdown?
Markdown is a lightweight markup language that lets you add formatting to plain text. It's used everywhere—from README files to documentation to blog posts.
Basic Syntax
**bold**or__bold__→ bold*italic*or_italic_→ italic# Heading 1,## Heading 2[link text](url)→ link→ image`code`→code
GitHub Flavored Markdown (GFM)
GFM extends basic Markdown with:
- Tables:
| A | B |with|---|---| - Task lists:
- [x] done,- [ ] todo - Strikethrough:
~~deleted~~ - Fenced code blocks:
```language
Markdown Common Issues
Issue: Code blocks not rendering
Cause: Not using fenced code blocks or missing language identifier.
Fix: Use triple backticks with optional language:
```javascript
const x = 1;
```Issue: Links not working
Cause: Usually incorrect syntax.
Fix: Make sure there's no space between brackets and parentheses:
[link](url) ✓ correct
[link] (url) ✗ wrongIssue: HTML not rendering
Cause: Some parsers sanitize HTML for security.
Solution: Don't mix HTML and Markdown unless your parser supports it.
