 ## Should I have faith in the predictions?
-Absolutely not. But it might help you learn how to use keras. 
+Absolutely not. 
 
 ## How it works
-Mynt uses an LSTM network to predict close prices for a user-specified number of days in the future. The training data is downloaded via [Alpha Vantage](https://www.alphavantage.co/) and requires that you request an API key. Currently
+Mynt uses an LSTM network to predict close prices for a user-specified number of days in the future. The training data is downloaded via [Alpha Vantage](https://www.alphavantage.co/).
 
 ## Usage
+First get an API key from Alpha Vantage. 
 To train a model for a  particular ticker
 ``` python
 model = getOrTrainModel(alpha_vantage_api_key, 'GE', scaler, epochs=100, look_back=look_back)
