 Configure Celery
 ----------------
 
 To improve |RCM| performance you should configure and enabled Celery_ as it makes
 asynchronous tasks work efficiently. Most important it allows sending notification
 emails, create repository forks, and import repositories in async way.
 
 If you decide to use Celery you also need a working message queue.
 The recommended message broker is rabbitmq_.
 
 
 In order to have install and configure Celery, follow these steps:
 
 1. Install RabbitMQ, see the documentation on the Celery website for
    `rabbitmq installation`_.
+
 2. Configure Celery in the
    :file:`home/{user}/.rccontrol/{instance-id}/rhodecode.ini` file.
-    Set the following minimal settings, that are set during
-    rabbitmq_ installation::
+   Set the following minimal settings, that are set during rabbitmq_ installation::
 
         broker.host =
         broker.vhost =
         broker.user =
         broker.password =
 
     Full configuration example is below:
 
     .. code-block:: ini
 
         # Set this section of the ini file to match your Celery installation
         ####################################
         ###        CELERY CONFIG        ####
         ####################################
         ## Set to true
         use_celery = true
         broker.host = localhost
         broker.vhost = rabbitmqvhost
         broker.port = 5672
         broker.user = rabbitmq
         broker.password = secret
 
         celery.imports = rhodecode.lib.celerylib.tasks
 
         celery.result.backend = amqp
         celery.result.dburi = amqp://
         celery.result.serialier = json
 
         #celery.send.task.error.emails = true
         #celery.amqp.task.result.expires = 18000
 
         celeryd.concurrency = 2
         #celeryd.log.file = celeryd.log
         celeryd.log.level = debug
         celeryd.max.tasks.per.child = 1
 
         ## tasks will never be sent to the queue, but executed locally instead.
         celery.always.eager = false
 
 
 3. Enable celery, and install `celeryd` process script using the `enable-module`::
 
     rccontrol enable-module celery {instance-id}
