+
+slideflow.io
+============
+
+This module contains utility functions for working with TFRecords, cross-compatible
+with both Tensorflow and PyTorch.
+
+Functions included in this module assist with processing TFRecords, detecting image and data format,
+extracting tiles, splitting and merging TFrecords, and a variety of other manipulations.
+
+Additional Tensorflow-specific TFRecord reading/writing utility functions are
+available in :py:mod:`slideflow.io.tensorflow`, and additional PyTorch-specific
+functions are in :py:mod:`slideflow.io.torch`.
