What this skill does

# Tutorial Documentation Skill

This skill provides patterns for writing effective tutorials following the Diataxis framework. Tutorials are learning-oriented content where the reader learns by doing under the guidance of a teacher.

## Purpose & Audience

**Target readers:**
- Complete beginners with no prior experience
- Users who want to learn, not accomplish a specific task
- People who need a successful first experience with the product
- Learners who benefit from guided, hands-on practice

**Tutorials are NOT:**
- How-To guides (which help accomplish specific tasks)
- Explanations (which provide understanding)
- Reference docs (which describe the system)

## Core Principles (Diataxis Framework)

### 1. Learn by Doing, Not by Reading

Tutorials teach through action, not explanation. The reader should be doing something at every moment.

| Avoid | Prefer |
|-------|--------|
| "REST APIs use HTTP methods to..." | "Run this command to make your first API call:" |
| "Authentication is important because..." | "Add your API key to authenticate:" |
| "The dashboard contains several sections..." | "Click **Create Project** in the dashboard." |

### 2. Deliver Visible Results at Every Step

After each action, tell readers exactly what they should see. This confirms success and builds confidence.

```markdown
Run the development server:

```bash
npm run dev
```

You should see:

```
> Local: http://localhost:3000
> Ready in 500ms
```

Open http://localhost:3000 in your browser. You should see a welcome page with "Hello, World!" displayed.
```

### 3. One Clear Path, Minimize Choices

Tutorials should not offer alternatives. Pick one way and guide the reader through it completely.

| Avoid | Prefer |
|-------|--------|
| "You can use npm, yarn, or pnpm..." | "Install the dependencies:" |
| "There are several ways to configure..." | "Create a config file:" |
| "Optionally, you might want to..." | [Omit optional steps entirely] |

### 4. The Teacher Takes Responsibility

If the reader fails, the tutorial failed. Anticipate problems and prevent them. Never blame the reader.

```markdown
<Warning>
Make sure you're in the project directory before running this command.
If you see "command not found", return to Step 2 to verify the installation.
</Warning>
```

### 5. Permit Repetition to Build Confidence

Repeating similar actions in slightly different contexts helps cement learning. Don't try to be efficient.

## Tutorial Template

Use this structure for all tutorials:

```markdown
---
title: "Build your first [thing]"
description: "Learn the basics of [product] by building a working [thing]"
---

# Build Your First [Thing]

In this tutorial, you'll build a [concrete deliverable]. By the end, you'll have a working [thing] that [does something visible].

<Note>
This tutorial takes approximately [X] minutes to complete.
</Note>

## What you'll build

[Screenshot or diagram of the end result]

A [brief description of the concrete deliverable] that:
- [Visible capability 1]
- [Visible capability 2]
- [Visible capability 3]

## Prerequisites

Before starting, make sure you have:

- [Minimal requirement 1 - link to install guide if needed]
- [Minimal requirement 2]

<Tip>
New to [prerequisite]? [Link to external resource] has a quick setup guide.
</Tip>

## Step 1: [Set up your project]

[First action - always start with something that produces visible output]

```bash
[command]
```

You should see:

```
[expected output]
```

[Brief confirmation of what this means]

## Step 2: [Create your first thing]

[Next action with clear instruction]

```code
[code to add or modify]
```

Save the file. You should see [visible change].

<Note>
[Optional tip to prevent common mistakes]
</Note>

## Step 3: [Continue building]

[Continue with more steps, each producing visible output]

## Step 4: [Add the final piece]

[Bring it together with a final step]

You should now see [final visible result].

## What you've learned

In this tutorial, you:

- [Concrete skill 1 - what they can now do]
- [Concrete skill 2]
- [Concrete skill 3]

## Next steps

Now that you have a working [thing], you can:

- **[Tutorial 2 title]** - Continue learning by [next learning goal]
- **[How-to guide]** - Learn how to [specific task] with your [thing]
- **[Concepts page]** - Understand [concept] in more depth
```

## Writing Principles

### Title Conventions

- **Start with action outcomes**: "Build your first...", "Create a...", "Deploy your..."
- Focus on what they'll make, not what they'll learn
- Be concrete: "Build a chat application" not "Learn about real-time messaging"

### Step Structure

1. **Lead with the action** - don't explain before doing
2. **Show exactly what to type or click** - no ambiguity
3. **Confirm success after every step** - "You should see..."
4. **Keep steps small** - one visible change per step

### Managing Prerequisites

Tutorials are for beginners, so minimize prerequisites:

```markdown
## Prerequisites

- A computer with macOS, Windows, or Linux
- A text editor (we recommend VS Code)
- 15 minutes of time

<Tip>
You don't need any programming experience. This tutorial explains everything as we go.
</Tip>
```

### The "You should see" Pattern

This is the most important pattern in tutorial writing. Use it constantly:

```markdown
Click **Save**. You should see a green checkmark appear next to the filename.

Run the test:

```bash
npm test
```

You should see:

```
PASS  src/app.test.js
  ✓ renders welcome message (23ms)

Tests: 1 passed, 1 total
```
```

### Handling Errors Gracefully

Anticipate failures and guide readers back on track:

```markdown
<Warning>
If you see "Module not found", make sure you saved the file from Step 2.
Return to Step 2 and verify the import statement matches exactly.
</Warning>
```

## Components for Tutorials

### Frame Component for Screenshots

Show what success looks like:

```markdown
<Frame caption="Your completed dashboard should look like this">
  ![Dashboard screenshot](/images/tutorial-dashboard.png)
</Frame>
```

### Steps Component for Procedures

For numbered sequences within a step:

```markdown
<Steps>
  <Step title="Open the settings panel">
    Click the gear icon in the top right corner.
  </Step>
  <Step title="Find the API section">
    Scroll down to **Developer Settings**.
  </Step>
  <Step title="Generate a key">
    Click **Create New Key** and copy the value shown.
  </Step>
</Steps>
```

### Callouts for Guidance

```markdown
<Note>
Don't worry if the colors look different on your screen.
We'll customize the theme in the next step.
</Note>

<Warning>
Make sure to save the file before continuing.
The next step won't work without this change.
</Warning>

<Tip>
You can press Cmd+S (Mac) or Ctrl+S (Windows) to save quickly.
</Tip>
```

### Code with Highlighted Lines

Draw attention to what matters:

```markdown
```javascript {3-4}
function App() {
  return (
    <h1>Hello, World!</h1>
    <p>Welcome to your first app.</p>
  );
}
```
```

## Example Tutorial

See [references/example-weather-api.md](references/example-weather-api.md) for a complete example tutorial demonstrating all principles above. The example builds a weather dashboard that fetches real API data.

## Checklist for Tutorials
