+### Activities
+Teapod uses a multi activity architecture. It is recommended not to use more activities than needed, but currently there are no other options than using multiple activities to support all needed features.
+* SplashActivity: is shown during startup, while MainActivity is being loaded
+* OnboardingAvtivity: Contains the on-boarding and login functions (currently only AoD)
+* MainActivity: As the name suggests, this contains the main gui
+* PlayerActivity: all player relates stuff goes here, separate activity to allow pip
