Your market is your readers.
The readers of your thesis are your examiners. They expect
details of all relevant parts of your research: why you did it, its
background, your thinking, what you did, your conclusions and
your views on where it is going. They don’t want the irrelevant
parts—details of how standard equipment works, for instance. Find
out as much as you can about content and format from your
supervisor and other students, and look at some recent
(successful) theses to get a feel for the product this market
expects.
