 ### Building New Benchmarks 
 
 All benchmarks inherit from the commom parent `Benchmark` class.

+Each benchmark overrides virtual functions for building the model, training,

 `def buildModel(self)`:
-returns a keras model
+Constructs and returns a keras model
 
 `def data_preprocess(self)`:
-returns X_train, y_train, X_test, y_test, X_tuner, and y_tuner data — in that order; this data will be directly used later for training and inference
+returns X_train, y_train, X_test, y_test, X_tuner, and y_tuner data (in that order): 
+These are described here:
+
+* `X_train:` Training data (fp32) in NCHW format
+* `y_train:` Training labels (int32)
+
+* `X_test:` Testing/Evaluation data in NCHW format
+* `y_test:` Testing/Evaluation labels
+
+* `X_tuner:` Data to be used for autotuning 
+* `y_tuner:` Labels corresponding to tuning data
+
 
 `def trainModel(self, model, X_train, y_train, X_test, y_test)`:
-returns a trained keras model
+Trains the Keras model constructed in `buildModel` and is expected to return the 
+trained keras model - training parameters should be tuned here.
 
 
+## Limitations 
 
+* We mosty support convolutional neural networks - RNNs/LSTMS are not supported
+* We currently only support models in NCHW format (NHWC is not supported)
+* Softmax operator should be the last operation in the CNN pipeline 
+* Softmax operation must be a separate operator (not specified as activation to another type of Keras operator)
