Discord is a voice and text chat application aimed at gamers but can be used by anyone. Is is currently available on Firefox, Opera, Chrome, Android, iPhone, Windows, OSX, and Linux….Basically everywhere. Installing Discord on Fedora 25 is easy.
Open a terminal and enable the copr repository.
sudo dnf copr enable vishalv/discord-canary
Then install with this command (You will have to accept the copr GPG key in order to install).
sudo dnf install discord-canary
It does seem to use a lot of resources on first start but after updating itself it should work just fine.
