+# DailyNode Discord Bot - Docker Setup
+
+## Quick Start
+
+### Using Docker Compose (Recommended)
+
+1. **Build and start the bot:**
+   ```bash
+   docker-compose up -d
+   ```
+
+2. **View logs:**
+   ```bash
+   docker-compose logs -f
+   ```
+
+3. **Stop the bot:**
+   ```bash
+   docker-compose down
+   ```
+
+4. **Restart the bot:**
+   ```bash
+   docker-compose restart
+   ```
+
+### Using Docker directly
+
+1. **Build the image:**
+   ```bash
+   docker build -t dailynode-bot .
+   ```
+
+2. **Run the container:**
+   ```bash
+   docker run -d \
+     --name dailynode-bot \
+     --env-file .env \
+     -v $(pwd)/config.json:/app/config.json \
+     --restart unless-stopped \
+     dailynode-bot
+   ```
+
+## Configuration
+
+Ensure your `.env` file contains:
+```env
+DISCORD_TOKEN=your_discord_bot_token
+clientId=your_client_id
+guildId=your_guild_id
+```
+
+## Maintenance
+
+**Update the bot:**
+```bash
+docker-compose down
+docker-compose build --no-cache
+docker-compose up -d
+```
+
+**View real-time logs:**
+```bash
+docker-compose logs -f dailynode
+```
+
+**Execute commands inside container:**
+```bash
+docker-compose exec dailynode sh
+```
+
+## Timezone
+
+The default timezone is set to `America/New_York`. To change it:
+1. Edit `docker-compose.yml`
+2. Change the `TZ` environment variable
+3. Restart: `docker-compose restart`
+
+## Data Persistence
+
+The `config.json` file is mounted as a volume to persist:
+- LeetCode channel configuration
+- Daily problem data
+
+This ensures your settings survive container restarts.
