How do I get rid of "Your title here" in the browser title bar?

I've used the older versions of the Atahualpa theme and there was a way to have a relevant title that I determined for each page showing up in the < title > tag. Of course I can't remember now and I can't find the thread on the forum that described that. Seems like there are some files missing that we used to be able to edit. Anyone know how to get my title into the title bar?

Thanks so much.
