+# Running a workload with Google Cloud ML Diagnostics Enabled
+This guide provides an overview on how to enable ML Diagnostics for your MaxText workload.
+
+## Overview
+Google Cloud ML Diagnostics is an end-to-end managed platform for ML Engineers to optimize and diagnose their AI/ML workloads on Google Cloud. The product allows ML Engineers to collect and visualize all their workload metrics, configs and profiles with one single platform, all within the same UI. The current product offering focuses on workloads running on XLA-based frameworks (JAX, Pytorch XLA, Tensorflow/Keras) on Google Cloud TPUs and GPUs. Current support is for JAX on Google Cloud TPUs only. 
+
+This feature can be enabled via a simple XPK command and is runnable across all supported environments, including Pathways and standalone TPU VMs by setting the **managed-mldiagnostics** flag in MaxText
+
+## Enabling ML Diagnostics on Maxtext Workload
+MaxText has integrated the ML Diagnostics SDK in its code. You can enable ML Diagnostics with the **managed-mldiagnostics** flag. If this is enabled, it will
+
+- create a managed MachineLearning run with all the MaxText configs
+- upload profiling traces, if the profiling is enabled by profiler="xplane".
+- upload training metrics, at the defined log_period interval.
+
+1. **Set your configuration**
+
+    ```
+    export PROJECT_ID="your-gcp-project-id"
+    export ZONE="your-gcp-zone" # e.g., us-central1-a
+    export CLUSTER_NAME="your-existing-cluster-name"
+    export BASE_OUTPUT_DIR="gs://your-output-bucket/"
+    export DATASET_PATH="gs://your-dataset-bucket/"
+    ```
+
+2.  **Configure gcloud CLI**
+
+    ```
+    gcloud config set project $PROJECT_ID
+    gcloud config set compute/zone $ZONE
+    ```
+
+### Run Maxtext via XPK
