All Enigma 2 images work in a very similar manner. Unfortunately there is no Enigma2 manual.
I am afraid it is a steep learning curve and most people are too afraid to say "i don't know" or "I don't understand". On the opposite side, if you pitch response too simplistically, people get offended because comments are seen as condescending.
Anyway, a good bunch of people here who will help you. Read and ask if/when you get stuck.
