Acquiring Polish passport

Wife is dual citizen-Poland, USA. She grew up on Poland and most of her family is in Warsaw but she lives with this American here in the States. She does have a 1/6 title ownership in her dad's apartment in Warsaw where we could live if needed.

So, here's the question. Does someone know the general flow of what I would have to do to achieve a Polish passport?

Just Google it … sh-citizen

Thank you. I'll read that.
