 ## Appendix: Install XPK for Multi-host Workloads
 
-**Note:** XPK is only required for multi-host TPU configurations (e.g., v5p-128, v6e-256). For single-host training, XPK is not needed and you can run MaxText directly on your TPU VM.

 XPK (Accelerated Processing Kit) is a tool designed to simplify the orchestration and management of workloads on Google Kubernetes Engine (GKE) clusters with TPU or GPU accelerators. In MaxText, we use XPK to submit both pre-training and post-training jobs on multi-host TPU configurations.
