+airtime-celery
+==============
+
+airtime-celery is a Celery_ daemon for handling backend tasks asynchronously.
+Communication and the Celery results backend are both handled with amqp (RabbitMQ).
+
+Installation
+============
+
+    $ sudo python setup.py install
+
+To install the configuration and upstart files for all environments (development and production)
+
+    $ sudo python setup.py install --all-envs
+
+You can also specify a single environment to deploy config and upstart files for:
+
+    $ sudo python setup.py install --dev-env=bananas
+
+Each instance of airtime-celery has its own worker, and multiple instances can be run in parallel.
+`Celery is thread-safe`_, so this parallelization won't cause conflicts.
+
+.. _Celery: http://www.celeryproject.org/
+.. _Celery is thread-safe: http://celery.readthedocs.org/en/latest/userguide/application.html
+
+Usage
+=====
+
+This program must be run with sudo:
+
+    $ sudo service airtime-celery {start | stop | restart | graceful | kill | dryrun | create-paths}
+
+Developers
+==========
+
+You may want to use the setuptools develop target to install:
+
+    $ sudo python setup.py develop
+
+You will need to allow the "airtime" RabbitMQ user to access all exchanges and queues within the /airtime vhost:
+
+    $ sudo rabbitmqctl set_permissions -p /airtime airtime .\* .\* .\*
+
+Logging
+=======
+
+By default, logs are saved to:
+
+    /var/log/airtime/airtime-celery[-DEV_ENV].log
