+As of version 0.4.0-rc0, the etcd backend is no longer supported.
 
 ## Overview
 
-Decider is a [feature flag](https://en.wikipedia.org/wiki/Feature_toggle) system with adaptable backends. It supports both `percentile` and `boolean` flags for controlled infrastructure rollouts and kill switches. Decider is built to be adaptable to any backing datastore. At the moment, [Consul](https://www.consul.io/intro/getting-started/kv.html), [Etcd](https://coreos.com/etcd/), and [Redis](http://redis.io/) are supported. [ZooKeeper](https://zookeeper.apache.org/) support is planned.
