-    # ### The best way to understand VADER is to look at the source code
-    # (Although it is a little unpolished) https://github.com/cjhutto/vaderSentiment
-    # 
-    # Also see the actual dictionary at https://github.com/cjhutto/vaderSentiment/blob/master/vaderSentiment/vader_sentiment_lexicon.txt.
-    # You can install the code using `pip install vaderSentiment` but it might be better to download it so you can more easily modify it.

-    # ### VADER doesn't run in Python 3 because of line 23 in vaderSentiment.py
