 If we want to build an AI/ML model, we need data. Lots and lots of data.
 
-For that, Riot Games has provided us with several HTTPs endpoints to make requests and obtain this data. Through the [sqlite_league.py](https://github.com/oracle-devrel/leagueoflegends-optimizer/blob/livelabs/src/sqlite_league.py) file, we'll be able to make all the kinds of requests we want. This Python file has been programmed to allow input parameters and determine the execution mode.
