 Kubeflow Training Operator is a Kubernetes-native project for fine-tuning and
 scalable distributed training of machine learning (ML) models created with various ML frameworks
-such as PyTorch, Tensorflow, XGBoost, MPI, Paddle and others.
+such as PyTorch, TensorFlow, HuggingFace, Jax, DeepSpeed, XGBoost, PaddlePaddle and others.
 
-Training Operator allows you to use Kubernetes workloads to effectively train your large models
-via [Kubernetes Custom Resources APIs](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/)
-or using Training Operator Python SDK.
-
-> Note: Before v1.2 release, Kubeflow Training Operator only supports TFJob on Kubernetes.
+You can run high-performance computing (HPC) tasks with the Training Operator and `MPIJob` since it
+supports running Message Passing Interface (MPI) on Kubernetes which is heavily used for HPC.
+The Training Operator implements the V1 API version of MPI Operator. For the MPI Operator V2 version,
+please follow [this guide](https://www.kubeflow.org/docs/components/training/user-guides/mpi/) to
+install MPI Operator V2.

 ## Prerequisites
 
-- Version >= 1.25 of Kubernetes cluster and `kubectl`
+Please check [the official Kubeflow documentation](https://www.kubeflow.org/docs/components/training/installation/#prerequisites)
+for prerequisites to install the Training Operator.
 
 ## Installation
 
-### Master Branch
+Please follow [the Kubeflow Training Operator guide](https://www.kubeflow.org/docs/components/training/installation/#installing-the-training-operator)
+for the detailed instructions on how to install Training Operator.
 
-```bash
-kubectl apply -k "github.com/kubeflow/training-operator/manifests/overlays/standalone"
-```
+### Installing the Control Plane
 
-### Stable Release
+Run the following command to install the latest stable release of the Training Operator control plane: `v1.8.0`.
 
 ```bash
-kubectl apply -k "github.com/kubeflow/training-operator/manifests/overlays/standalone?ref=v1.7.0"
+kubectl apply -k "github.com/kubeflow/training-operator.git/manifests/overlays/standalone?ref=v1.8.0"
 ```
 
-### TensorFlow Release Only
-
-For users who prefer to use original TensorFlow controllers, please checkout `v1.2-branch`, patches for bug fixes will still be accepted to this branch.
+Run the following command to install the latest changes of the Training Operator control plane:
 
 ```bash
-kubectl apply -k "github.com/kubeflow/training-operator/manifests/overlays/standalone?ref=v1.2.0"
+kubectl apply -k "github.com/kubeflow/training-operator/manifests/overlays/standalone"
 ```
 
-### Python SDK for Kubeflow Training Operator
+### Installing the Python SDK
 
-Training Operator provides Python SDK for the custom resources. To learn more about available
-SDK APIs check [the `TrainingClient`](sdk/python/kubeflow/training/api/training_client.py).
+The Training Operator [implements a Python SDK](https://pypi.org/project/kubeflow-training/)
+to simplify creation of distributed training and fine-tuning jobs for Data Scientists.
 
-Use `pip install` command to install the latest release of the SDK:
+Run the following command to install the latest stable release of the Training SDK:
 
 ```
-pip install kubeflow-training
+pip install -U kubeflow-training
 ```
 
-Training Operator controller and Python SDK have the same release versions.

+## Reference
 
-This project was originally started as a distributed training operator for TensorFlow and later we merged efforts from other Kubeflow training operators to provide a unified and simplified experience for both users and developers. We are very grateful to all who filed issues or helped resolve them, asked and answered questions, and were part of inspiring discussions. We'd also like to thank everyone who's contributed to and maintained the original operators.
