+"""
+Example demonstrating the separation of scheduler and worker.
+This script runs the scheduler part. You need to be running both this and the worker
+script simultaneously in order for the scheduled task to be run.
+
+Requires the "postgresql" service to be running.
+To install prerequisites: pip install sqlalchemy asyncpg
+To run: python async_scheduler.py
+
+When run together with async_worker.py, it should print a line on the console
+on a one-second interval.
