Boil time question

I just received the Lakefront Fixed Gear and have a question about the boil time. The instructions recommend a 90 minute boil but it states that once I boil the LME then add hops at 60 minutes. Does this mean I let the wort boil for 30 minutes before adding the hops?

That is how I would do it.

Yep, that’s exactly what it means.
