 # Iris: Synchronous and Distributed Blackbox Optimization at Scale
 
+## Overview
+Iris is a library for performing synchronous and distributed zeroth-order
+optimization at scale. It is meant primarily to train large neural networks with
+evolutionary methods, but can be applied to optimize any high dimensional
+blackbox function.
