The Manual (How to Have a Number One the Easy Way) is a 1988 book by The Timelords (Bill Drummond and Jimmy Cauty), better known as The KLF. It is a step by step guide to achieving a No.1 single with no money or musical skills, and a case study of the duo's UK novelty pop No. 1 "Doctorin' the Tardis".
It was the most popular music act in the world (or at least Europe) for a couple of years in the 90's. They owned and ran their own label. At the height of their success they deleted their entire back catalogue and all the physical records they created, in an attempt to remove themselves from the music industry, and they would have succeeded if they hadn't then gone on and burnt a million pounds in a small Scottish island which was something that people would not forget.
