--For dummies

For Dummies is an extensive series of instructional reference books which are intended to present non-intimidating guides for readers new to the various topics covered. The series has been a worldwide success with editions in numerous languages. The books are an example of a media franchise, consistently sporting a distinctive cover—usually yellow and black with a triangular-headed cartoon figure known as the "Dummies Man", and an informal, blackboard-style logo. Prose is simple and direct; bold icons, such as a piece of string tied around an index finger, are placed in the margin to indicate particularly important passages.
