+Management Commands
+-------------------
+
+If you want to schedule regular Django management commands, you can use the :mod:`django.core.management` module to make a wrapper function which you can schedule in Django Q::
+
+	# tasks.py	
+	from django.core import management
+			
+	# wrapping `manage.py clearsessions`
+	def clear_sessions_command():
+	    return management.call_command('clearsessions')
+
+	# now you can schedule it to run every hour
+	from django_q import schedule
+
+	schedule('tasks.clear_sessions_command', schedule_type='H')
