+# OpenTelemetry Collector Kubernetes Distro
+
+This distribution is made specifically to be used in a Kubernetes Cluster to monitor Kubernetes and services running in Kubernetes. It contains a subset of components from [OpenTelemetry Collector](https://github.com/open-telemetry/opentelemetry-collector) and [OpenTelemetry Collector Contrib](https://github.com/open-telemetry/opentelemetry-collector-contrib).
+
+## Components
+
+The full list of components is available in the [manifest](manifest.yaml)
+
+### Rules for Component Inclusion
+
+ - Only includes components from Contrib and Core.
+ - Only components that are Alpha or higher.
+ - All receivers must facilitate the collection of data that is generated by Kubernetes or services running in Kubernetes 
+   - Although you could run a collector in Kubernetes to reach out to any endpoint, this distribution is not targeting that use case. This distribution is for monitoring Kubernetes and the processes it runs. 
+ - All components must be vendor-neutral.
+ - Only exporters that use OTLP are allowed.
+   - To facilitate troubleshooting, the debug exporter and file exporter are exceptions .
+ - All technologies OTel promised to support will be included as receivers. Specifically this means the `jaegerreceiver`, `zipkinreceiver`, `opencensusreceiver`, and `prometheusreceiver` will be included.
