Well, not really tips. Last year, I wrote two two blog posts about my initial working with Scrivener. They might help some people with getting to grips with it.
Post 1: “Now, I’m a believer”
Post 2: “Stripped-down Scrivener”
I’m no expert, and don’t profess to be even a good writer, but I’ve found Scrivener extremely useful in my writing. Maybe you will too.
