No default theme anymore?

Hi there,
Is it possible to get a default theme in ionic 2? From what i understand there used to be one included, which is good enough for me, I just dislike small, grey squares as buttons.
Styling is not my cup of tea so anything instead of no css at all would be nice.

Ouch, noticed that the tutorial I was following was three months old, outdated that is. No more “royal” or “block”, “ion-button” gave some candy instead.
