# Write documentation

This skill covers how to write and update tldraw SDK documentation.

## Location

All documentation lives in `apps/docs/content/`. The main categories are:

| Directory          | Purpose                                       |
| ------------------ | --------------------------------------------- |
| `docs/`            | SDK documentation articles                    |
| `releases/`        | Release notes (see write-release-notes skill) |
| `examples/`        | Example documentation                         |
| `getting-started/` | Quickstart and setup guides                   |

## Process

### 1. Understand the scope

Before writing:

- Identify the target audience (new users, experienced developers, API reference)
- Check existing docs that cover related topics
- Look at relevant examples in `apps/examples/`
- Read the API types and comments in the source code

### 2. Create the file

Create a new `.mdx` file in the appropriate directory with frontmatter:

```yaml
---
title: Feature name
status: published
author: steveruizok
date: 3/22/2023
order: 1
keywords:
  - keyword1
  - keyword2
---
```

### 3. Write the content

Follow the structure:

1. **Overview** — 1-2 paragraphs on what and why
2. **Basic usage** — The simplest working example
3. **Details** — Deeper explanation with more examples
4. **Edge cases** — Advanced patterns, gotchas
5. **Links** — Related docs and examples

### 4. Use MDX components

#### API links

Use `[ClassName](?)` or `[ClassName#methodName](?)` for API references:

```markdown
The [Editor](?) class has many methods. Use [Editor#createShapes](?) to create shapes.
```

#### Code highlighting

Use `<FocusLines>` to highlight specific lines:

```markdown
<FocusLines lines={[2,6,10]}>

\`\`\`tsx
import { Tldraw } from 'tldraw'
import { useSyncDemo } from '@tldraw/sync'
\`\`\`

</FocusLines>
```

#### Images

```markdown
<Image
	src="/images/api/events.png"
	alt="A diagram showing an event being sent to the editor."
	title="Caption text here."
/>
```

#### Tables for API documentation

Use tables for listing methods, options, or properties:

```markdown
| Method                   | Description                                    |
| ------------------------ | ---------------------------------------------- |
| [Editor#screenToPage](?) | Convert a point in screen space to page space. |
| [Editor#pageToScreen](?) | Convert a point in page space to screen space. |
```

```markdown
| Value     | Description                                          |
| --------- | ---------------------------------------------------- |
| `default` | Sets the initial zoom to 100%.                       |
| `fit-x`   | The x axis will completely fill the viewport bounds. |
```

### 5. Verify

Check that:

- Code examples actually work
- API links resolve correctly
- Images have alt text
- Headings use sentence case
- No AI tells (see style guide)
