Markdown Syntax Fundamentals

Core markdown syntax for creating well-structured documents.

Headings

# Heading 1
## Heading 2
### Heading 3
#### Heading 4
##### Heading 5
###### Heading 6

Heading Best Practices

Use a single H1 (
```
#
```
) per document as the title
Don't skip heading levels (H2 to H4)
Keep headings concise and descriptive
Use sentence case or title case consistently

Text Formatting

Emphasis

*italic* or _italic_
**bold** or __bold__
***bold italic*** or ___bold italic___
~~strikethrough~~

Inline Code

Use `backticks` for inline code like `const x = 1`

Lists

Unordered Lists

- Item one
- Item two
  - Nested item
  - Another nested item
- Item three

* Alternative marker
+ Also works

Ordered Lists

1. First item
2. Second item
   1. Nested numbered
   2. Another nested
3. Third item

Task Lists (GitHub Flavored)

- [x] Completed task
- [ ] Incomplete task
- [ ] Another task

Links

Basic Links

[Link text](https://example.com)
[Link with title](https://example.com "Title text")

Reference Links

[Link text][reference-id]

[reference-id]: https://example.com "Optional title"

Automatic Links

<https://example.com>
<email@example.com>

Internal Links (Anchors)

[Jump to section](#section-heading)

Anchor IDs are auto-generated from headings:

Lowercase
Spaces become hyphens
Special characters removed

Images

Basic Images

![Alt text](image.png)
![Alt text](image.png "Optional title")

Reference Images

![Alt text][image-id]

[image-id]: path/to/image.png "Optional title"

Best Practices

Consistent formatting: Pick a style and stick to it
Blank lines: Add blank lines before and after:
- Headings
- Code blocks
- Lists
- Blockquotes
Line length: Consider wrapping at 80-120 characters for readability
Alt text: Always provide meaningful alt text for images
Link text: Use descriptive link text, not "click here"
Code highlighting: Always specify language for fenced code blocks
