Since the Quest itself is a full computer with a processor, memory, and screen (those are the lenses), the ELEVEN software is also downloaded and installed within the goggles. This is very easy and self-explanatory. You can also download the Oculus software onto the PC and connect the glasses to the PC via WLAN. This has several advantages.
you can make adjustments to the glasses without having to put them on
you can stream what you see in the glasses to PC or Fire Stick or Chromecast so others can watch you play table tennis.
A controller posture that gives the haptic the finishing touch.
You don't necessarily need the paddle, you can definitely play excellently with the controllers that are already included. I use it because it's even closer to the real thing, because the grip is the same thickness as a regular table tennis bat grip and the thumb and forefinger positions are also almost identical. the downside is that the racquet is then slightly top-heavy, but this is adjustable with the solidslime that I recommend.

If you use a paddle, you have to tell the software, which expects a different bracket. To do this, go to the menu item Setup (gear symbol) and paddle, from then on you will find your way around.
