spotify stations

Hey all!
I just heard about the Spotify stations app. I like the whole switch as you swipe thing. But, I do have some questions. I have looked @ the directions on the app entry on here, but I can't get it to work. My questions are:
1. how do you remove artists from stations?
2. how do you add artists 2 a station?
I can double tap & hold & it gives me a list of artists a particular station was created from. But that's all. The app is 100% accessible & I love it, & I know I've only had this app for a few minutes, but I'd appreciate any of your help on this. Thanks in advance!

#1 Adding Artists

Tap "search" to look for the artist you want.
When you find it, double tap that artist's name.
It will take you into a page with similar artists.
I believe the original artist is selected. So if you want to add any of the others, double tap them.
If you want to add other artists, double tap "search" again, double tap on your chosen artist which will be selected, and check out the suggested artists along with that one.
If you don't want to add any of the suggestions, you can just keep searching and adding your preferred artists.
When you have added all you want, go down to the bottom of the page, and double tap "next."
This will take you to a page where you can rename the station.
After doing that, click "done" and you have a new station.
I am not sure if you can add any more artists after this point.
I don't think you can remove artists from a station, but you can "thumbs down" them until they stop playing on that station.

You can also swipe up on station to activate. Context menu will open. There you can add suggested artists, search for artists. I believe they limit amount of artists you can add. You can’t remove artists, but you can remove station and start over.
