How to get the app - Hoid/LoL-Performance-Tracker GitHub Wiki

Downloading and running this app

If you are simply a user who wants to try out the app, you can do so pretty easily. Download the ZIP file of the repository (the button for which can be found on the right of the main page) and go into the /dist/LoL-Performance-Tracker directory. Run LoL-Performance-Tracker.exe. It will ask you for two things: your summoner name and your API key. If you don't have a summoner name, you can use mine: Transatlantacism. If you need an API key, register over at https://developer.riotgames.com.

Once you input these, you're done! The app should take at least a minute to download your match history. After you do this the first time, you won't have to again.
