-## Compatibility with Cluster API and Kubernetes Versions
+## Compatibility with Cluster API
 
 - BYOH is currently compatible wth Cluster API v1beta1 (v1.0)
-- BYOH installer support is present and tested only for Kubernetes version `v1.22.3`. You may however use it to provision clusters of a different version by manually installing the Kubernetes components (use the `--skip-installation` flag when starting the agent)
