Configuring an IRC channel in Quassel

I am trying to add channels in Quassel but I am totally lost, I have tried Googling it but got nowhere!

As a test, I’m trying to add this one;
But I’m not getting anywhere?

Here’s a screenshot of the settings I’ve added.

I’ve sorted it.
I click on the ‘Ubuntu Chat’ and up pops a ‘#’ list and when I click on one, it takes me there and when I leave, it saves it under ‘Ubuntu Chat’

Good, because that Quassel is a KDE app and wanted to pull in a TON of dependencies … so I was kinda hoping someone else would step in.
