 To train your own neural net, use one of our FER neural net classes to get started. You can try the convolutional_model.py example:
 
 ```
-python convolutional_example.py
-```
+python convolutional_model.py
+``` 
 
 The example first initializes the model. A summary of the model architecture will be printed out. This includes a list of all the neural net layers and the shape of their output. Our models are built using the Keras framework, which offers this visualization function.
