 python-watcherclient
 ====================
 
-Python client library for Watcher API.
+Client for resource optimization service for OpenStack.
 
-Watcher takes advantage of CEP and ML algorithms/metaheuristics to improve physical resources usage through better VM placement. Watcher can improve your cloud optimization by reducing energy footprint and increasing profits.
+OpenStack Watcher provides a flexible and scalable resource optimization
+service for multi-tenant OpenStack-based clouds.
+Watcher provides a complete optimization loop—including everything from a
+metrics receiver, complex event processor and profiler, optimization processor
+and an action plan applier. This provides a robust framework to realize a wide
+range of cloud optimization goals, including the reduction of data center
+operating costs, increased system performance via intelligent virtual machine
+migration, increased energy efficiency—and more!
