Go to https://uicard.io/ and click the little button in the bottom right. The developer can answer your questions best. I would not buy a theme, there are plenty of nice themes on the Theme Site. The only reason would probably be to have a developer at hands that can do individual work. There is a lot of “lorem ipsum” on that page and links that go to 404s. Not trust inducing
@nicovon, your question is confusing because you are asking about a pro version, as if you are using it. Please ask questions framed about Hugo here.
Please read the docs for Hugo. It explains how content is created. After your read the docs about hugo new and archetypes, you may ask specific questions in #support.
