+
+This is a simple Rust library that includes all kinds of helper methods, structs and enums that can be used to write a Kubernetes Controller/Operator with the [kube-rs](https://github.com/kube-rs/kube-rs) crate.
+
+It is part of the Stackable Data Platform, a curated selection of the best open source data apps like Apache Kafka, Apache Druid, Trino or Apache Spark, [all](#our-operators) working together seamlessly. Based on Kubernetes, Stackable is designed to run on prem or in the cloud.
+
+## Documentation
+
+This project is not featured in our main documentation documents. The code contains doc comments, and you can find explanations of high-level concepts
+in the main documentation of the Stackable products at [docs.stackable.tech](https://docs.stackable.tech).
+
+To see examples of how operator-rs is being used, take a look at the codebases of our [operator repositories](#our-operators).

+
+## About The Stackable Data Platform
+
+This operator is written and maintained by [Stackable](https://stackable.tech) and it is part of a larger data platform.
+
+![Stackable Data Platform Overview](./.readme/static/borrowed/sdp_overview.png)
+
+Stackable makes it easy to operate data applications in any Kubernetes cluster.
+
+The data platform offers many operators, new ones being added continuously. All our operators are designed and built to be easily interconnected and to be consistent to work with.
+
+The [Stackable GmbH](https://stackable.tech/) is the company behind the Stackable Data Platform. Offering professional services, paid support plans and custom development.
+
+We love open-source!
