 preloadManager on the same player instance.
 The preloading process loads the manifest and first segments of the asset. It
 will not load the whole asset ahead of time.
+If you need to define any response or request filters for your assets to be
+downloaded, remember to do it before calling `player.preload`.
 
 The preload method can be provided an optional startTime and mimeType parameter,
 much the same as the load method.
