+# Overview
+
+ICS consists of two main modules:
+
+* [x/provider](./02-provider.md)
+  * Provides to consumer chains updated information of opted in validators.
+  * Distributes ICS rewards to opted in validators.
+  * Jails and slashes validators that misbehave on consumer chains.  
+* [x/consumer](./03-consumer.md)
+  * Sends to the consensus engine the validator sets received from the provider chain.
+  * Splits consumer block rewards and sends ICS rewards to the provider chain. 
+  * Notifies the provider chain of downtime infractions. 
+
+Note that `x/types` contains types shared by both modules.
+
+In addition, the following modules are added to ICS to extend its functionality:
+
+* [x/democracy](04-democracy.md)
