+Install RabbitMQ for asynchronous tasks
+=======================================
+
+In order to launch asynchronous tasks (useful for huge imports for example), we use RabbitMQ.
+
+Requirements
+------------
+
+You need to have RabbitMQ installed on your server.
+
+Installation
+~~~~~~~~~~~~
+
+.. code:: bash
+
+  wget https://www.rabbitmq.com/rabbitmq-signing-key-public.asc
+  apt-key add rabbitmq-signing-key-public.asc
+  apt-get update
+  apt-get install rabbitmq-server
+
+Configuration and launch
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. code:: bash
+
+  rabbitmq-plugins enable rabbitmq_management # (useful to have a web interface, available at http://localhost:15672/ (guest/guest)
+  rabbitmq-server -detached
+
+Stop RabbitMQ
+~~~~~~~~~~~~~
+
+.. code:: bash
+
+  rabbitmqctl stop
+
+
+Configure RabbitMQ in wallabag
+------------------------------
+
+Edit your ``parameters.yml`` file to edit RabbitMQ configuration.
+
+Launch RabbitMQ consumer
+------------------------
+
+Put this command in a cron job:
+
+.. code:: bash
+
+  bin/console rabbitmq:consumer entries -w
