+Install Redis for asynchronous tasks
+=======================================
+
+In order to launch asynchronous tasks (useful for huge imports for example), we can use Redis.
+
+Requirements
+------------
+
+You need to have Redis installed on your server.
+
+Installation
+~~~~~~~~~~~~
+
+.. code:: bash
+
+  apt-get install redis-server
+
+Launch
+~~~~~~
+
+The server might be already running after installing, if not you can launch it using:
+
+.. code:: bash
+
+  redis-server
+
+
+Configure Redis in wallabag
+---------------------------
+
+Edit your ``parameters.yml`` file to edit Redis configuration. The default one should be ok:
+
+.. code:: yaml
+
+    redis_host: localhost
+    redis_port: 6379
+
+
+Launch Redis consumer
+------------------------
+
+Depending on which service you want to import from you need to enable one (or many if you want to support many) cron job:
+
+.. code:: bash
+
+  # for Pocket import
+  bin/console wallabag:import:redis-worker pocket -vv >> /path/to/wallabag/var/logs/redis-pocket.log
+
+  # for Readbility import
+  bin/console wallabag:import:redis-worker readability -vv >> /path/to/wallabag/var/logs/redis-readability.log
+
+  # for wallabag v1 import
+  bin/console wallabag:import:redis-worker wallabag_v1 -vv >> /path/to/wallabag/var/logs/redis-wallabag_v1.log
+
+  # for wallabag v2 import
+  bin/console wallabag:import:redis-worker wallabag_v2 -vv >> /path/to/wallabag/var/logs/redis-wallabag_v2.log
+
+If you want to launch the import only for some messages and not all, you can specify this number (here 12) and the worker will stop right after the 12th message :
+
+.. code:: bash
+
+  bin/console wallabag:import:redis-worker pocket -vv --maxIterations=12
