Almost all commercially printed recipes will END with 0 minutes. Cascade hops are aroma hops meaning they're added near the end so for this recipe it's most definitely saying to add at the end of the boil. If something says 60 minutes, you add when your clock reads 60 (most likely the beginning of your boil). If it says 45, add when your clock reads 45. 30 minutes, your clock reads 30:00. Very simple stuff.
Rule of thumb: I usually steep my grains with a grain bag until the water reaches about 170. I then remove the grain bag, wait for the wort to come to a boil, turn off the heat, add any LME, stir to dissolve it, and then bring the wort to a boil. I then allow it to boil for 5 minutes before adding the first hop addition. At this point I start the 60 minute clock.
