+## Additional Notes
+
+Note that the train and test protocol definition for the network is in the `lenet_train_test.prototxt` file which differs from the `lenet.prototxt` file. In `lenet_train_test.prototxt file`, layers may include one additional definition, like the one below:
+
+
+    layers {
+      
+      // Other layer definitions
+
+      include: { phase: TRAIN }
+    }
+
+This layer will be used only in training phase. If we change `TRAIN` with `TEST`, then this layer will be used only in test phase. Otherwise this layer will be used in both training and test phase. Thus `lenet_train_test.prototxt` has two `DATA` layers defined (with different `batch_size`), one for training and one for testing.

 ## Training and Testing the Model
 
-Training the model is simple after you have written the network definition protobuf and solver protobuf files. Simply run `train_mnist.sh`, or the following command directly:
