+## Configure and Launch DBOS Properly
+
+Every DBOS application must configure and launch DBOS inside the main function.
+
+**Incorrect (configuration at module level):**
+
+```python
+from dbos import DBOS, DBOSConfig
+
+# Don't configure at module level!
+config: DBOSConfig = {
+    "name": "my-app",
+}
+DBOS(config=config)
+
+@DBOS.workflow()
+def my_workflow():
+    pass
+
+if __name__ == "__main__":
+    DBOS.launch()
+    my_workflow()
+```
+
+**Correct (configuration in main):**
+
+```python
+import os
+from dbos import DBOS, DBOSConfig
+
+@DBOS.workflow()
+def my_workflow():
+    pass
+
+if __name__ == "__main__":
+    config: DBOSConfig = {
+        "name": "my-app",
+        "system_database_url": os.environ.get("DBOS_SYSTEM_DATABASE_URL"),
+    }
+    DBOS(config=config)
+    DBOS.launch()
+    my_workflow()
+```
+
+For scheduled-only applications (no HTTP server), block the main thread:
+
+```python
+import os
+import threading
+from dbos import DBOS, DBOSConfig
+
+@DBOS.scheduled("* * * * *")
+@DBOS.workflow()
+def scheduled_task(scheduled_time, actual_time):
+    pass
+
+if __name__ == "__main__":
+    config: DBOSConfig = {
+        "name": "my-app",
+        "system_database_url": os.environ.get("DBOS_SYSTEM_DATABASE_URL"),
+    }
+    DBOS(config=config)
+    DBOS.launch()
+    threading.Event().wait()  # Block forever
+```
