+Discord installations from Linux package managers may not work well with moonlight (due to root permissions or immutability). It is suggested to install Discord locally into a path like `~/.local/share`. A script to install Discord locally (maintained by a community member) is available [here](https://gist.github.com/maddymeows/6af1a5d5a870c13b7b159c4463edee70).
