Missing something in the theory book

Are you missing something in the theory book? That’s possible. The theory book is constantly updated. You can send me your contribution via WhatsApp. For example, if you want to read or learn more about trailers and their rules, send me your proposed text, and I will add your contribution, provided it is correct, of course, to the theory book. Simple questions, such as I don’t understand priority, will, of course, not be added. For questions like this, you can go to our Facebook page: https://www.facebook.com/groups/theoriecursus
