Added details to WiVRn section. Mostly pulled from the WiVRn Github, Personal experience, and aspects mentioned elsewhere in the wiki that I believe should also be mentioned here.

 We recommend using [Envision](/docs/fossvr/envision/) to install and launch WiVRn & OpenComposite. Envision will handle all configuration seamlessly and avoids many of the pitfalls of a manual setup.
 
+Alternatively, you can use the [WiVRn Flatpak](https://flathub.org/apps/io.github.wivrn.wivrn) which includes OpenComposite as part of it.

+## General WiVRn Notes
+
+To use WiVRn you need to have Avahi installed and running. You can ensure it is running with the following terminal command:
+```bash
+systemctl enable --now avahi-daemon
+```
+If you have a firewall installed, you will need to ensure ports 5353/UDP and 9757/UDP+TCP are open for Avahi and WiVRn itself, respectively.
+
+If you are using Nvidia proprietary drivers, you will need to have [Monado Vulkan Layers](https://gitlab.freedesktop.org/monado/utilities/vulkan-layers) installed to play any steam games with WiVRn.
+
+For audio in WiVRn, you will need to assign applications, or the system as a whole, to output audio to the virtual output "WiVRn" which is created upon connection between the server and the headset.

 ## Wired WiVRn
 
 Use WiVRn with a cable instead of Wifi. Use a 5Gbps cable & port at the very least.
