I'm Jean-Christophe Hoelt, from Fovea, main developer of the In-App Purchase plugin. I built this guide for you as a collection of step-by-step recipes, each focusing on one specific goal. As soon as you know what your goal is, I will try to explain all the required steps to achieve it. I'll also give you general details about what the In-App Purchase technology is, how it works and what it can do for you.
