Markdown Reference

Atlas notes use standard Markdown. If you’ve written markdown before, everything you know already works. This page is a quick cheat sheet you can refer back to.

Headings

# Heading 1
## Heading 2
### Heading 3
#### Heading 4

Use headings to organize sections within a note. Heading 1 (#) is typically your note title.

Text formatting

**bold text**
*italic text*
~~strikethrough~~

Renders as: bold text, italic text, ~~strikethrough~~

You can combine them: **_bold and italic_**

Lists

Bullet list:

- First item
- Second item
  - Nested item
  - Another nested item
- Third item

Numbered list:

1. First step
2. Second step
3. Third step

Numbered lists stay in order even if you rearrange them — just use 1. for every item and the renderer handles the numbering.

Task checkboxes

- [ ] Buy groceries
- [ ] Finish the proposal
- [x] Send weekly update

Renders as interactive checkboxes. Tasks with [x] are marked complete. Atlas can read, add, and toggle tasks in your notes via the task tools.

Links

External link:

[Link text](https://example.com)

Wiki-link to another note:

[[Note Name]]
[[Note Name|Custom display text]]

Wiki-links connect your notes together and appear in your network graph. See Linking Notes for more.

Images

![Alt text](./images/screenshot.png)
![Alt text](https://example.com/image.jpg)

Images can be relative paths (files inside your vault) or full URLs. The alt text is shown if the image can’t load and is important for accessibility.

Code

Inline code:

Use `console.log()` to debug.

Code block with syntax highlighting:

```python
def hello():
    print("Hello, Atlas!")
```

Supported languages include python, javascript, typescript, rust, bash, sql, json, yaml, markdown, and many more.

Tables

| Name       | Role       | Status  |
|------------|------------|---------|
| Alex       | Designer   | Active  |
| Jordan     | Engineer   | On leave |

Columns align automatically. You can left-, center-, or right-align columns:

| Left | Center | Right |
|:-----|:------:|------:|
| text | text   | text  |

Blockquotes

> This is a quoted passage or important callout.
>
> It can span multiple paragraphs.

Blockquotes are useful for quotations, key takeaways, or highlighting important text.

Horizontal rules

---

A horizontal rule creates a visual divider between sections. Three or more hyphens on a line by themselves.

Frontmatter

---
title: My Note
date: 2026-02-24
tags: [work, ideas]
---

YAML frontmatter goes between the two --- lines at the very top of a file. See Tags and Frontmatter for full details.
