I recently received the following two stars review:
I do not understand ... to be more specific step by step ...
If he paid a little attention instead of rushing to write negative reviews he would have noticed that in the main menu there is a button labeled "User Manual" which when pressed magically shows the user manual with the description step by step that he needed.
To the left of each button there is also a small blue icon that when pressed shows a small contextual help.
Here you can find the complete manual.
