 ### Optimizer and Scheduler
 
 As long as you don't enable `offload_optimizer` you can mix and match DeepSpeed and HuggingFace schedulers and
-optimizers, with the exception of using the combination of HuggingFace scheduler and DeepSpeed optimizer:
+optimizers.

 It is possible to use a non-DeepSpeed optimizer when `offload_optimizer` is enabled, as long as it has both CPU and
 GPU implementation (except LAMB).
