+# Kubedoop Operator for Apache Hadoop
+
+This is a Kubernetes operator to manage Apache Hadoop HDFS clusters.
+
+It's part of the kubedoop Data Platform, a modular open source data platform built on Kubernetes that provides Kubernetes native deployment
+and management of popular open source data apps like Apache Kafka, Apache Doris, Apache Kyuubi, Trino or Apache Spark, all working
+together seamlessly. Based on Kubernetes, it runs everywhere – on prem or in the cloud.
