It would be very nice to have some clear documentation for Dolibarr. It would be well worth the 15 euro price. However, with no readable sample of the writing, there is no way to evaluate if the linked documentation is worth the price. An image of the cover and three unreadable screenshots of the table of contents are pretty much worthless. I don’t see any way to contact the seller to ask for more information about this product. Can you help with that hORb?
