 ## Motivation
 
-The [CloudEvents specification](https://github.com/cloudevents/spec) is vendor-neutral specification for defining the format of event data that is being exchanged between different cloud systems. The specification basically defines an abstract envelope for any event data payload, without knowing specific implementation details of the actual underlying event. The current version of the spec is at `0.2` and it describes a simple event format, which was demonstrated at last [KubeCon 2018](https://youtu.be/TZPPjAv12KU) using different _Serverless platforms_, such as [Apache Openwhisk](https://github.com/apache/incubator-openwhisk).
