Styling import

Has the location of the import for styles been changed?
In the docs it suggest "@dialectlabs/react-ui/index.css" but this doesn't connect to anything.
Searching through github issues I found that "@dialectlabs/react-ui/lib/index.css" does work though.

Also I can't seem to find any information about customizing styles of components. At the moment I've just copy/pasted the css file mentioned above to my repo and I'm changing stuff there, but there's certainly a better way.
