 We use an image classification model, CIFAR10, and a language model, BERT, to demonstrate pretraining on Windows with DeepSpeed.
 
 ## Pretraining CIFAR10
-The scripts and codes required for CIFAR10 pretraining example are available in the following path: DeepSpeedExamples\training\cifar. You can launch the CIFAR10 pretraining experiment using the following command: `deepspeed cifar10_deepspeed.py –deepspeed`. The final output should look something like this:
