Deleted my Tutorial Text?

I recently downloaded the trial version of Scrivener, slowly learning how it works. However, I think I bungled when I got to Part 3. I don’t think I completely got out of Step 13: Collection in the part before and somehow I deleted what was on Part 3’s page. I’m not sure what I did, sorry. Can any one tell me what is supposed to be on Step 3? I still have parts 14, 15, 16 intact, it is just that first page that is blank.
