 This is a work in progress. It was inspired by another trending repo I saw on github. I wanted to see if I could do my own implementation of it, as a learning exercise.
 
-**Tested in Python 2.7, 3.4 and 3.5**
+**Tested in Python 2.7 and >=3.3**
 
 ## Setup
 **To use this you will need an api key from api.football-data.org. Without this the program will still work but will be limited to 50 requests per day.**
 
 Once you have your key, you must set an environment variable called `PYSCORES_KEY` so the program can use it.
