The PDF build does not include content multiple times if the same file is included in a toctree more than once. That means we need to restructure the guide to handle the common parts differently. This approach merges some of the previously split sections back together using inline prose to indicate where minor variations apply for different operating systems but retaining separate files for cases where the differences are significant.
