Once you can navigate the Scrivener system it's brilliant, but to begin with it can be daunting. You can find out more about the possible downside here, but now I've been working with Scrivener for a while these are my top tips:
1. There's no substitute for diving in and tinkering. Use the free trial facility available from Literature and Latte. Press all the buttons, switch from view to view, drag and drop, and try out various forms of compilation to create different types of document for publication or upload. You can customise the system, so that each time you start a new project the fonts and formatting are exactly as you want them. Take your time to become familiar with the whole Scrivener experience. It's lovely to open a new project and start typing, knowing you're free to work without having to fight the system. Which leads me to...
2. Never try to learn a new system such as Scrivener when you're working to a deadline. Learn first, write later. Or write using your normal word processor (regularly saving to flash drives or the cloud, of course) then import it into the Scrivener project where you store all your research and ideas. I did this when I was working on my latest short romance, My Dream Guy. I wrote the first draft in a single document, using Pages for Mac. Instead of giving each chapter a title, I put a hashtag (#) at the end of each one. When imported into Scrivener, the system automatically created a new file for each chapter. After editing my work in Scrivener, all I needed to do to format it ready for publication was hit Scrivener's "compile" button and—bingo! One ready-formatted manuscript, ready to go.
4. Scrivener For Dummies, written by Scrivener Wizard Gwen Hernandez is an invaluable book, although in common with every other trouble-shooting system for computing I've used, if you don't know why you're stuck, it won't be much help. You need to know the exact questions to ask the index, and the terms to use. I found fiddling about free-form (see Tip 1, above) and then cross-referencing the effect I achieved with this book was a great way to learn. I've always got my copy within reach. As a result, it's covered with notes, and remnants of those two vital components of a writer's life, tea and cake. Gwen Hernandez also has a Scrivener Corner on her website, with loads of useful tips (and no cake crumbs). You can find that here.
5. If all else fails, type your question into a search engine. You'll be amazed how many articles and YouTube videos have been produced by enthusiasts. A word of warning: because these people are enthusiasts, you may find the instructors go too fast, or skip over exactly the details you need to know. More than one of these personable geniuses uses the phrase "you'll know how to do that already...." about the precise part of the process you want explained. The screenshots these video artistes use are often tiny and indistinct, too, so use these only if you've got 20/20 vision, a degree in mind-reading, and you're willing to take a chance.
