Stalling on adding Pages controller


Hi, I'm just starting out and trying to figure out if I am making a mistake or if this course is just a bit buggy. I'm trying to add the home method to the pages controller, but everything keeps freezing. Also, the Pages controller doesn't show up like the other files, I need to link in manually, so maybe things are going wrong sooner. Anyone else having this problem or know what approach to take to detect errors here?
