+Wanna contribute on adding games with pictures and backgrounds? Now you can! Just do a pull request editing the [Games List.json](https://github.com/MrCoolAndroid/Xbox-Rich-Presence-Discord/blob/main/Games%20List.json) file!
+- "titlename" should have the original name of the game that shows on Xbox, remove any Copyright or Trademark symbols
+- Images on "titleicon" should be 1024x1024, and "titlebackground" can be any size but choose one that fits on the app correctly
+- "titleimage" is a Discord parameter, give it any name or the game name, i will edit it after the pull request
+
+Remember, edit the complete code and add your game array, make sure to add  
+any necessary commas and brackets  
+
+I will check the code later, edit it with my titleimage and merge it if everything is ok.
