Hello Gerben, I am a beginner myself, and working on a book project too. Below I send you my complete directory setup with sample files. I am happy with the set-up and it might also be useful for you. Matthias Directory structure: sas.tex % main project file layout.tex % main layout file screenbook/screenbook.tex % product file part1/chapter1/chapter1.tex part1/chapter1/section1/section1.tex And here the files: % sas.tex: \startproject sas \environment layout \product screenbook/screenbook \stopproject %layout.tex % contains definitions and 'styles' relevant for all products \startenvironment layout \setuppagenumbering[location={footer,middle}] \setuphead [chapter] [numberstyle=bold, textstyle=cap, before=\hairline\blank, after={\nowhitespace\hairline\blank[line]}] \stopenvironment % screenbook/screenbook.tex % contains definitions for the relevant product % Maybe this can be moved to a secondary environment file, % I haven't tried that yet. \startproduct screenbook \setupcolors[state=start] \project sas \setuppapersize[S6][S6] \startfrontmatter \starttext \startstandardmakeup \midaligned{My Little Book --- Screen Version} \midaligned{by} \midaligned{Myself} \stopstandardmakeup \stoptext \completecontent \stopfrontmatter \startbodymatter \component part1/part1 \component part2/part2 \component part3/part3 \component part4/part4 \stopbodymatter \startbackmatter \completeindex \stopbackmatter \stopproduct % part1/chapter1/chapter1.tex \chapter{My first chapter} \starttext This is about whatever I have to say. \input part1/chapter1/section1/section1 \stoptext % part1/chapter1/section1/section1.tex % put all helper (images etc) files in this directory, too % This file contains the actual text and doesn't see the project structure % anymore. \section{My first section} blah blah blah
