Welcome to the Cafe and to Painter Essentials. PE4 is a terrific program I'm sure you'll enjoy for a long time to come, and the Cafe is a great place to learn from others (and eventually teach what you know) and share your paintings and experiences.
Yes, there's a written guide to the video tutorials. In Essentials, under the Help menu at the top of your screen, you'll see "Guidebook". Click on that and what you're looking for will open up. You can read it onscreen or print it out. Enjoy!
