+Rally job
+=========
+
+We provide, with Watcher, a Rally plugin you can use to benchmark the optimization service.
+
+To launch this task with configured Rally you just need to run:
+
+::
+
+  rally task start watcher/rally-jobs/watcher.yaml
+
+Structure
+---------
+
+* plugins - directory where you can add rally plugins. Almost everything in
+  Rally is a plugin. Benchmark context, Benchmark scenario, SLA checks, Generic
+  cleanup resources, ....
+
+* extra - all files from this directory will be copy pasted to gates, so you
+  are able to use absolute paths in rally tasks.
+  Files will be located in ~/.rally/extra/*
+
+* watcher.yaml is a task that is run in gates against OpenStack
+  deployed by DevStack
+
