so at the moment i am writing a document in the class article. But i want the header you have when you use documentclass "book". I dont use class the "book" though because my document is not so long that i could use the chapter-command that generates those giant headlines. Is there a way to get the headers from the documentclass "book" or can i use the documentclass book somehow and use the normal \section command for the table of content? Because at the moment it puts an "0" in front of all my sections.
Thank you
