To help you get started the following Links to useful information will be a good place to start - viewtopic.php?p=57531#p57531
If you've not already done so it's worth signing up for the monthly newsletter where we hope to share case studies, new techniques and product information. You'll find access to past newsletters here as well as the option to sign up at the bottom of the page - https://www.picoauto.com/library/newsletter-archive.
I hope this helps and feel free to ask and contribute.
