Spent all day following these instructions:

In most cases, the simplest approach is to copy stuff over from an existing site (I used French). Sometimes it helps to screenshot the working site and copy settings from it (because you can't have two simultaneous sessions on Cascade in different locations, even with different browsers). I have virtually everything working except for the News and Events page, which is strangely borked, and the unit logo, which I think needs to be done by an official graphics person.
