 We use a simple Python script to hit the Untappd API. We use R to make graphs and run stats.
 
+## Requirements

+Install [Docker Desktop](https://docs.docker.com/desktop/) for your system.

 ### Getting Untappd API Secrets
 
 To run the Python script, you'll need an Untappd `CLIENT_ID` and `CLIENT_SECRET`. Put those in the `.env` file in the root of project, like so:
 
 ```
-echo "CLIENT_ID=123" >> .env
-echo "CLIENT_SECRET=456" >> .env
+cd python; echo "CLIENT_ID=123" >> .env; echo "CLIENT_SECRET=456" >> .env
 ```
 
 You'll need to apply for an [Untappd API key](https://untappd.com/api/docs).
 
 You'll also need to put USERNAMES in the `.env` file as a list, like so:
 
 ```
-echo "USERNAMES=alexdannylow,andrewbogo" >> .env
+echo "USERNAMES=alexdannylow,andrewbogo,DylanHong" >> .env
 ```
 
 The users cannot be private on Untappd.
