+### The ImageNet Dataset in keras_cv
+
+In order to load ImageNet with KerasCV, you'll need to download the [original ImageNet dataset](https://image-net.org) and parse the images into TFRecords.
+
+Tensorflow provides a [script](https://github.com/tensorflow/tpu/blob/master/tools/datasets/imagenet_to_gcs.py) to perform this parsing and upload images to Google Cloud Storage (or optionally to local storage).
+
+Please reference that script's instructions on producing ImageNet TFRecords, and then use the KerasCV loader to load records from wherever you choose to store them.
