Altaria (hereinafter the "Application") is a Discord bot that provides gentle reminders to users when they upload images without alt-text descriptions, promoting accessibility and inclusion within Discord communities.

## 1. User Documentation

This section is for those interacting with a live instance of the Application.

### What is Altaria?

Altaria is a friendly Discord bot designed to encourage the use of alt-text (alternative text) for images in Discord servers. Alt-text helps make content accessible to users who rely on screen readers and assistive technologies.

### How to Add Altaria to Your Server

1. Use the official invitation link: [Add to Discord](https://discord.com/oauth2/authorise?client_id=1405356559214837860)
2. Select your server from the dropdown menu
3. Grant the necessary permissions:
   - Read Messages/View Channels
   - Send Messages
   - Use Slash Commands

### How Altaria Works

- **Automatic Monitoring**: Altaria monitors messages in channels where it has permissions
- **Image Detection**: When someone posts an image without alt-text, Altaria detects it automatically
- **Gentle Reminders**: The bot responds with one of 100 carefully crafted, encouraging messages
- **Educational Links**: Each reminder includes helpful resources about adding alt-text and writing descriptions

### Using Slash Commands

Altaria supports slash commands that provide information about the bot:
- Type `/` and select an Altaria command to learn more about the bot's features and purpose

### Reminder Message Categories

Altaria's reminders fall into five themed categories:
1. **Gentle Encouragement** (20 messages) - Soft, supportive reminders
2. **Playful/Cute** (20 messages) - Fun, anime-inspired messages with emoticons
3. **Educational** (20 messages) - Informative content about accessibility
4. **Community Vibes** (20 messages) - Emphasising collective responsibility
5. **Thematic/Fantasy** (20 messages) - Creative, story-driven reminders
