 - `DEBUG` : If set to anything except `false`, will put bot into debug mode. This means that all actions will be logged into the chat itself, and more things will be logged.
 - `ADMIN_EXEMPT` : If set to anything except `false`, admin users will be exempt from monitoring. Reccomended to be set, but useful to turn off for debugging.
 - `NOTIFY_CHAT` : ID of chat to report actions. Can be useful if you have an admin-only chat where you want to monitor the bot's activity. E.g. `-140532994`
+- `CMC_API_KEY`: If you want the `/price` bot command to work, make sure to set a CoinMarketcap API key

+## Download the corpus for Textblob
+
+For sentiment analysis to work, you'll need to download the latest corpus file for textblob. You can do this by running:

+python -m textblob.download_corpora
