 Nextcloud Talk is really easy to install. You just need to enable the app from the [Nextcloud App Store](https://apps.nextcloud.com/apps/spreed) and everything will work out of the box.
 
-There are some scenarios (users behind strict firewalls / symmetric NATs) where a TURN server is needed. That's a bit more tricky installation, but the guys from [Nextcloud VM](https://github.com/nextcloud/vm) has developed a script which takes care of everything for you.

Please keep in mind that it's developed for the VM specifically and any issues should be reported in that repo, not here.
