May I join you asking for a documentation?
I feel a little lost and since I could not find any other similar post in the forum, I am afraid I do not see the obvious: the how to. First problem is always the translation. When there is a lot texts to be translated in the administration and you do not know exactly, where it will be used for, on which page it will appear or when exactly which email will be sent ... difficult. Often it is just a guess, what I fill into the forms.
But the other question I hardly dare to ask: what when all this is done? How do I really offer a product or service? How do I create a product, how do I place it on the site, how do I put a shopping cart (or whatever) button on it.
Where do I find a documentation? FAQs only refer to another component as does the demo, the short version of the payment form description I do not understand or at least not fully.
Makes me really feel stupid.
