excellent book for people who do not start the specialty. each step is described in great detail and many many photos and diagrams provide the necessary clarity in the implementation of work. I had already purchased when it appeared there a few years ago because I followed (and still am the) courses, leisure activities, I have offered and recommended to all my friends; and lately I have offered to a group of adult students in accelerated vocational training (with the consent of the teacher), because I think it can help them to 'swallow' and better assimilate the theoretical learning and practical. So I advise this book to non-beginners and people in vocational training, as a complementary support their learning.
