Conceptual Documentation

Explains concepts and architecture.

# Authentication Architecture

## Overview

The authentication system uses JWT tokens for stateless authentication.

## Components

### Token Service

Responsible for generating and validating tokens.

### Session Manager

Manages user sessions and refresh tokens.

## Flow

1. User submits credentials
2. Server validates credentials
3. Server generates JWT token
4. Client stores token
5. Client sends token with requests
6. Server validates token on each request

## Security Considerations

- Tokens expire after 1 hour
- Refresh tokens valid for 30 days
- Tokens are signed with RS256

Writing Patterns

Inverted Pyramid

Start with the most important information:

# Feature X

Feature X allows you to do Y. Use it when you need Z.

## Quick Start

\`\`\`typescript
// Most common usage
doFeatureX()
\`\`\`

## Details

More detailed explanation...

## Advanced Usage

Edge cases and advanced scenarios...

Progressive Disclosure

Layer information from simple to complex:

# Configuration

## Basic Configuration

\`\`\`json
{
  "apiKey": "your-key"
}
\`\`\`

## Standard Options

| Option | Type | Default |
|--------|------|---------|
| timeout | number | 30000 |
| retries | number | 3 |

## Advanced Options

For fine-grained control...

## Expert Configuration

For specialized use cases...

Task-Oriented

Organize around what users want to accomplish:

# User Management

## Common Tasks

### Add a New User
...

### Update User Permissions
...

### Remove a User
...

### Reset User Password
...

Formatting Guidelines

Code Blocks

\`\`\`typescript
// Always specify the language
const example = true
\`\`\`

\`\`\`bash
# Use bash for shell commands
npm install package
\`\`\`

\`\`\`json
{
  "use": "json for config"
}
\`\`\`
