Documentation Standards

File Naming Convention

• Use 01-, 02-, 03- prefix for sequential ordering
• Use kebab-case for file names after prefix
• Use descriptive names (e.g., 02-adding-new-bolt.md not 02-new-bolt.md)
• Group related files in numbered subdirectories

Content Structure

Each markdown file should follow this structure:

---
sidebar_position: [auto-determined by number prefix]
title: [Human-readable title]
---

# Title

## Prerequisites
What reader should know before this document

## Main Content
[Content sections with H2, H3 headings]

## What You Learned

Code Block Standards

• Always specify language for syntax highlighting
• Include comments for complex code
• Show both working examples and common mistakes
• Use line highlighting for important sections

Diagram Standards

• Use Mermaid for all diagrams
• Include alt text descriptions
• Keep diagrams simple and focused
• Use consistent color schemes and styles

import TabItem from '@theme/TabItem';

<Tabs>
  <TabItem value="kotlin" label="Kotlin">

    // code
    ```
  </TabItem>
  <TabItem value="config" label="Configuration">
    ```yaml
    # config
    ```
  </TabItem>
</Tabs>

```kotlin {2,5-7}
fun example() {
    val important = "highlighted"
    val normal = "not highlighted"

    // These lines
    // are also
    // highlighted
}

## Sequential Navigation Flow

The documentation is designed to be read in order:

01-introduction → 02-setup → 03-architecture → 04-core-concepts → 05-components → 06-development → 07-configuration → 08-deployment → 09-api-reference → 10-guides → 11-reference

Within each section, files are numbered sequentially (01-, 02-, 03-, etc.) to guide readers through the learning path naturally.
