 The code implements a multilayer perceptron to train the MNIST data. The code demonstrates the use of the "SimpleBind"  C++ API and CSVIter. The CSVIter can iterate data that is in CSV format. The example can be run on CPU or GPU. The example usage is as follows:
 
 ```
-build/mlp_csv --train mnist_training_set.csv --test mnist_test_set.csv --epochs 10 --batch_size 100 --hidden_units "128,64,64 [--gpu]"
+build/mlp_csv --train data/mnist_data/mnist_train.csv --test data/mnist_data/mnist_test.csv --epochs 10 --batch_size 100 --hidden_units "128 64 64" --gpu
+```
+* To get the `mnist_training_set.csv` and `mnist_test_set.csv` please run the following command:
+```python
+# in incubator-mxnet/cpp-package/example directory
+python mnist_to_csv.py ./data/mnist_data/train-images-idx3-ubyte ./data/mnist_data/train-labels-idx1-ubyte ./data/mnist_data/mnist_train.csv 60000
 
 Review comment:
   do we have instructions on how to get train-images & train-labels locally?
