+Prerequisites
+=============
+
+1. Yarn app of Ray is run under the Hadoop environment version 2.8.0.
+   You can get the Hadoop binary from
+   `here <http://archive.apache.org/dist/hadoop/common/hadoop-2.8.0/hadoop-2.8.0.tar.gz>`__.
+
+Walkthrough
+===========
+
+Yarn environment and configuration
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Firstly, you should have an available hadoop yarn environment and
+configuration.
+
+Prepare ray on yarn jar file
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. code:: shell
+
+    $ make clean package
+
+Prepare deploy zip file
+^^^^^^^^^^^^^^^^^^^^^^^
+
+.. code:: shell
+
+    $ cd deploy
+    $ zip -r deploy.zip .
+
+Please modify the script 'deploy/run.sh' on-demand.
+
+Run
+^^^
+
+.. code:: shell
+
+    $ /path/to/hadoop-2.8.0/bin/yarn jar ./target/ray-on-yarn-1.0.jar  org.ray.on.yarn.Client  --jar ./target/ray-on-yarn-1.0.jar --rayArchive ./deploy/deploy.zip --containerVcores 2 --containerMemory 2048 --priority 10 --shellCmdPriority 10 --numRoles 1 1 --queue ray --headNodeStaticArgs "'--num-cpus 4 --num-gpus 4'" --workNodeStaticArgs "'--num-cpus 2 --num-gpus 2'"
+
+Please modify the command line on-demand. Some detail about the input
+args is in the help doc.
+
+.. code:: shell
+
+    /path/to/hadoop-2.8.0/bin/yarn jar ./target/ray-on-yarn-1.0.jar  org.ray.on.yarn.Client --help
+
+Monitoring
+^^^^^^^^^^
+
+Please check the logs depend on your yarn platform.
+
+Stop
+^^^^
+
+.. code:: shell
+
+    $ /path/to/hadoop-2.8.0/bin/yarn application -kill {app_id}
+
+``{app_id}`` shall be replaced by the ID of the corresponding Yarn
+application, e.g. ``application_1505745052163_0107``.
