+## Supported Keras Operators 
+
+The Keras frontend supports `Sequential()` Keras models.
+The list of supported operations is as follows:
+
+* `Conv2D`
+* `DepthwiseConv2D`
+* `Dense`
+* `BatchNormalization`
+* `MaxPooling2D`
+* `AveragePooling2D`
+* `Flatten`
+* `Add`
+* `ZeroPadding2D`
+* `Activation` 
+   * `relu`
+   * `tanh`
+   * `softmax`
+
+
+
+## Limitations 
+
+* We support convolutional neural networks that include the supported operators above - 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)
