## Quick Start - Docker (Recommended)

```bash
# Copy and edit environment file
copy .env.example .env
# Edit .env with your Reddit credentials

# Start the bot
docker-compose up -d

# View logs
docker-compose logs -f
```

See [DOCKER.md](DOCKER.md) for detailed Docker setup instructions.

## Customizing Posts with Wiki Configuration

The bot loads post templates from your subreddit's wiki page `minecraft_update_bot`. This allows you to:
- Create different post formats for releases vs. snapshots
- Customize titles and bodies without restarting
- Support legacy version types with custom messages

**Quick Setup:**
1. Create a wiki page named `minecraft_update_bot` on your subreddit
2. Add YAML configuration with your templates (see example below)
3. Bot auto-loads every 30 minutes

**Simple Example:**
```yaml
release:
  title: "Minecraft {version} Released!"
  body: |
    # Minecraft {version}
    Available now! Get it at [minecraft.net](https://minecraft.net)
    **Released:** {release_date}

snapshot:
  title: "Minecraft {version} Snapshot"
  body: |
    # New Snapshot Available
    Test {version} before the official release!
```

👉 See [WIKI_CONFIG.md](WIKI_CONFIG.md) for complete setup and examples.

## Bedrock Edition Support

The bot can track **Minecraft Bedrock Edition (Windows)** releases in addition to Java Edition.

**To enable Bedrock tracking:**

1. **With Docker:** Add to your `.env` file:
   ```
   CHECK_BEDROCK=true
   ```

2. **Manual:** Set environment variable before running:
   ```bash
   set CHECK_BEDROCK=true
   python main.py
   ```

3. **Configure Bedrock posts** in your wiki page (optional):
   ```yaml
   bedrock-windows:
     title: "Minecraft Bedrock {version} Available (Windows)"
     body: |
       # Bedrock Edition {version}
       Download from the Microsoft Store
       **Released:** {release_date}
   ```

The bot will now check for both Java and Bedrock releases every cycle, posting about each separately.

## Manual Setup

### 1. Install Dependencies

```bash
pip install -r requirements.txt
```

### 2. Create Reddit Application

1. Go to [https://www.reddit.com/prefs/apps](https://www.reddit.com/prefs/apps)
2. Click "Create an app" or "Create another app"
3. Fill in the form:
   - **Name:** MinecraftUpdateBot
   - **App type:** Script
   - **Redirect URI:** http://localhost:8080
4. Copy the credentials

### 3. Configure the Bot

Edit `config.py` and fill in your credentials:

```python
REDDIT_CLIENT_ID = "YOUR_CLIENT_ID"  # From app page
REDDIT_CLIENT_SECRET = "YOUR_CLIENT_SECRET"  # From app page
REDDIT_USERNAME = "YOUR_USERNAME"  # Your Reddit username
REDDIT_PASSWORD = "YOUR_PASSWORD"  # Your Reddit password
SUBREDDIT = "YOUR_SUBREDDIT"  # Subreddit to post to
```

Or use environment variables (Docker-friendly):

```bash
set REDDIT_CLIENT_ID=your_client_id
set REDDIT_CLIENT_SECRET=your_client_secret
set REDDIT_USERNAME=your_username
set REDDIT_PASSWORD=your_password
set SUBREDDIT=your_subreddit
python main.py
```

### 4. Customize (Optional)

In `config.py`:
- **RELEASE_TYPES:** Change `["release"]` to include snapshots or other types
  - Options: `"release"`, `"snapshot"`, `"old_beta"`, `"old_alpha"`
- **CHECK_INTERVAL:** How often to check for updates (in seconds)
  - Default: 3600 (1 hour)
- **POST_TEMPLATE:** Customize the post format

Examples:
```python
# Check for both releases and snapshots
RELEASE_TYPES = ["release", "snapshot"]

# Check every 30 minutes
CHECK_INTERVAL = 1800

# Check every 10 minutes (for testing)
CHECK_INTERVAL = 600
```

### 5. Run the Bot

```bash
python main.py
```

You should see output like:
```
[BOT] Starting Minecraft Update Bot...
[BOT] ✓ Successfully connected to Reddit
[BOT] Started update checker (checking every 3600 seconds)
[BOT] ✓ Bot is running
```

## Automatic Update Notifications

The bot includes an update checker that periodically polls for new versions and notifies your subreddit's modteam via modmail when updates are available.

**How it works:**
- Checks `https://updts.slfhstd.uk` every hour for new versions
- Sends modmail to your subreddit's modteam if an update is found
- Limits notifications to once per 24 hours to avoid spam
- No configuration needed - it runs automatically!

**What you'll see:**
```
[UPDATE_CHECKER] Started for MinecraftUpdateBot v1.0
[UPDATE_CHECKER] Update found: 1.0 -> 1.1
[UPDATE_CHECKER] Sent update notification to r/your_subreddit
```

The modteam will receive a message with the new version number and changelog link.

## How It Works

1. **Initialization:** Bot connects to Reddit and loads posted versions from `DB/posted_versions.json`
2. **Check Loop:** Every CHECK_INTERVAL seconds, it:
   - Fetches the latest Minecraft versions from Mojang's launcher manifest
   - Checks if any are new (not in `DB/posted_versions.json`)
   - Posts to subreddit if new versions found
   - Saves the posted version IDs
3. **Background:** Runs in background thread, checking continuously

## Database

Posted versions are stored in `DB/posted_versions.json`:

```json
{
  "posted": [
    "1.20.1",
    "1.21",
    "1.21.1"
  ]
}
```

To reset (post all new versions again), delete or clear this file.

## Troubleshooting

### Connection Issues
- Check your credentials in `config.py` or environment variables
- Verify your Reddit app is configured correctly
- Make sure your Reddit account can post to the subreddit

### "No New Releases"
- The bot only posts once per version
- Check `DB/posted_versions.json` to see what's been posted
- Delete a version from the file to repost it

### Test with Snapshots
Change `RELEASE_TYPES = ["snapshot"]` and `CHECK_INTERVAL = 60` to test quickly.
