+QuoteForge now includes automated cron jobs for maintenance tasks. These can be run using the built-in cron functionality in the Docker container.
+
+### Docker Compose Setup
+
+The Docker setup includes a dedicated cron service that runs the following jobs:
+
+- **Alerts check**: Every hour (0 * * * *)
+- **Price updates**: Daily at 2 AM (0 2 * * *)
+- **Usage counter reset**: Weekly on Sunday at 1 AM (0 1 * * 0)
+- **Popularity score updates**: Daily at 3 AM (0 3 * * *)
+
+To enable cron jobs in Docker, run:
 
 ```bash
-go run ./cmd/server -migrate
+docker-compose up -d
 ```
 
+### Manual Cron Job Execution
+
+You can also run cron jobs manually using the quoteforge-cron binary:
+
+```bash
+# Check and generate alerts
+go run ./cmd/cron -job=alerts
+
+# Recalculate all prices
+go run ./cmd/cron -job=update-prices
+
+# Reset usage counters
+go run ./cmd/cron -job=reset-counters
+
+# Update popularity scores
+go run ./cmd/cron -job=update-popularity
+```
+
+### Cron Job Details
+
+- **Alerts check**: Generates alerts for components with high demand and stale prices, trending components without prices, and components with no recent quotes
+- **Price updates**: Recalculates prices for all components using configured methods (median, weighted median, average)
+- **Usage counter reset**: Resets weekly and monthly usage counters for components
+- **Popularity score updates**: Recalculates popularity scores based on supplier quote activity
