 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 to install. You can [find instructions in our documentation](https://nextcloud-talk.readthedocs.io/en/latest/TURN/) and the team behind the Nextcloud VM has developed a script which takes care of everything for you ([vm-talk.sh](https://github.com/nextcloud/vm/blob/master/apps/talk.sh)). The script is tested on Ubuntu Server 18.04, but should work on 16.04 as well. Please keep in mind that it's developed for the VM specifically and any issues should be reported in that repo, not here.

-### Milestones and Branches
-
-#### Branches
-
-In the Talk app we have one branch per Nextcloud server version. stable* branches of the app should always work with the same branch of the Nextcloud server.
-This is only off close to releases of the server, to allow easier finishing of features, so we don't have to backport them.
-
-#### Milestones
-
-* 10.0.0 - **Numeric** milestones are settled and waiting for their release or some final polishing
-* 💛 Next Minor (20) - The **next minor** milestone is for issues/PR that go into the next Dot-Release for the given Nextcloud version (in the example 20 - e.g. 10.0.1)
-* 💚 Next Major (21) - The **next major** milestone is for issues/PR that go into the next feature release for the new Major Nextcloud version (as there are Minors for 20, this would be 21)
-* 💔 Backlog - The **backlog** milestone is assigned to all remaining issues
-
-You can always pick a task of any of the milestones and we will help you to get it into the assigned milestone or also an earlier one if time permits. It's just a matter of having an overview and better visibility what we think should be worked on, but it's not exclusive.
