 ### Name Format
 ```
-minecraft-pi-reborn-<Variant>_X.Y.Z~<Distribution>_<Architecture>
+minecraft-pi-reborn-<Variant>_X.Y.Z_<Architecture>
 ```
 
 ### Picking A Variant
 * ``client``: Client mode, use this if you want to play MCPI
 * ``server``: Server mode, use this if you want to host a dedicated MCPI server
 
-### Picking A Distribution
-This specifies which version of Debian MCPI-Reborn was built against. Which one you should use depends on your current distribution. If your distribution supports it, you should use ``bullseye`` for better mouse sensitivity.
-
-* Ubuntu 20.04+: ``bullseye``
-* Raspberry Pi OS Buster: ``buster``
-* Debian Bullseye+: ``bullseye``
-* Debian Buster: ``buster``
-
 ### Picking An Architecture
 * ``amd64``: x86_64, use this if you are using a device with an AMD or Intel processor
 * ``armhf``: ARM 32-Bit, use this if you are using an ARM device (like a Raspberry Pi)

+# Sound
+One of MCPI-Reborn's main modifications is a sound-engine since MCPI doesn't include one by default[^1]. However, it can't be used out-of-box because MCPI doesn't contain any sound data and MCPI-Reborn can't include it because of copyright.
+
+MCPE's sound data can be extracted from any MCPE v0.6.1[^2] APK file, just place its `libminecraftpe.so` into `~/.minecraft-pi/overrides` and you should have sound!
+
+[^1]: The mute button is just leftover code from MCPE, it doesn't actually do anything in un-modded MCPI, however it is connected to MCPI-Reborn's sound-engine.
+[^2]: This isn't a hard limit, an MCPE v0.8.1 APK would probably work, but don't rely on it.
