+# Overview
+
+The Client API (xxDK) is the client-side software for communicating with the cMix network, a privacy protecting layer within the larger xx network. cMix builds on current data protection mechanisms by extending security beyond just content to include metadata — the what, when, where, and how of user activity.
+
+The xxDK helps developers provide unparalleled privacy for their users by implementing xx network messaging features such as end-to-end encryption and metadata protection. It comes with an API library and related command line facilities that enable developers build full-featured xx clients for all platforms. Additionally, the base messaging protocols can be extended.
+
+Some use cases for integrating the API into your applications include (but are not limited to) building:
+
+- Banking applications
+- Voting applications, such as [Votexx](https://votexx.org/)
+- Secure messaging apps for private communications
