 ### Playing Audio (Basic Commands)
 
 To set up player with audio to play, use either: 
-* `initializeSavedAudio(withSavedUrl url: URL, mediaInfo: SALockScreenInfo?)` to play audio that is saved on the device.
-* `initializeRemoteAudio(withRemoteUrl url: URL, mediaInfo: SALockScreenInfo?)` to play audio streamed from a remote location.
+* `startSavedAudio(withSavedUrl url: URL, mediaInfo: SALockScreenInfo?)` to play audio that is saved on the device.
+* `startRemoteAudio(withRemoteUrl url: URL, mediaInfo: SALockScreenInfo?)` to play audio streamed from a remote location.
 
 Both of these expect a URL of the location of the audio and an optional media information to display on the lockscreen.
