    REDDIT_CLIENT_SECRET=your_client_secret
    REDDIT_USERNAME=your_username
    REDDIT_PASSWORD=your_password
    REDDIT_USER_AGENT=modreplybot by /u/your_username
    REDDIT_SUBREDDIT=your_subreddit
    REDDIT_WIKI_PAGE=modreplybot-config
    LOG_LEVEL=Default
    ```

    ## Installation

    ### Docker Compose (Recommended)
    1. Copy `.env.example` to `.env` and fill in your values.
    2. Run:

    ```
    docker compose up -d
    ```

    * The DB folder is mounted for persistent database storage.

    ### Docker Run
    1. Copy `.env.example` to `.env` and fill in your values.
    2. Run:

    ```
    docker run --env-file .env -v $(pwd)/DB:/app/DB slfhstd.uk/slfhstd/modreplybot:latest
    ```

    ### Baremetal (Direct Python)
    1. Install Python 3.11+
    2. Install dependencies:

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

    3. Set environment variables or create a `.env` file.
    4. Run:

    ```
    python modreplybot.py
    ```

    ## Chat-Based Config Reload
    - To reload the wiki config, send a chat message containing `reload-config` to the bot account from a moderator account.
    - The bot will reply to the chat message indicating whether the config is valid or not.
    - Chat message IDs are tracked in `/DB/chat_wiki_requests.txt` to prevent duplicate reloads after restarts.

    ## Troubleshooting
    - Ensure your Reddit credentials are correct and have moderator permissions.
    - The bot must be able to read the wiki page and approve posts.
    - Check logs for errors.
    - The bot only responds to mod comments and mod reports for triggers.
    - Database is stored in `/DB/commented_posts.txt` and `/DB/chat_wiki_requests.txt` and survives container restarts.
    - If the wiki config is invalid, the bot will reply to the chat message with an error.
