-The `kfp-kubernetes` Python library enables authoring [Kubeflow pipelines](https://www.kubeflow.org/docs/components/pipelines/v2/) with Kubernetes-specific features. These features are supported by the [default KFP open source BE](https://github.com/kubeflow/pipelines/tree/master/backend). Specifically, the `kfp-kubernetes` library supports authoring pipelines that use:
+The Kubeflow Pipelines SDK kfp-kubernetes python library (part of the [Kubeflow Pipelines](https://www.kubeflow.org/docs/components/pipelines/) project) is an addon to the [Kubeflow Pipelines SDK](https://kubeflow-pipelines.readthedocs.io/) that enables authoring Kubeflow pipelines with Kubernetes-specific features and concepts, such as:

+The `kfp-kubernetes` package can be installed as a KFP SDK extra dependency.
 ```sh
-pip install kfp[kubernetes] --pre
+pip install kfp[kubernetes]

 Or installed independently:

 ```
 
-## Example usage
-<!-- TODO: test these examples once the BE implementation exists -->
-### Secret: As environment variable
-```python
-from kfp import dsl
-from kfp import kubernetes
+## Getting started
 
-@dsl.component
-def print_secret():
-    import os
-    print(os.environ['SECRET_VAR'])
+The following is an example of a simple pipeline that uses the kfp-kubernetes library to mount a pre-existing secret as a volume to a task's container.
 
-@dsl.pipeline
-def pipeline():
-    task = print_secret()
-    kubernetes.use_secret_as_env(task,
