That looks like a really useful resource, but seriously -- EXE or CHM files? I would have thought that a huge chunk of the people likely to be deploying nginx would be on either OSX or Linux machines...
That does seem a bit weird. Anyway the Nginx manual is quite good in it self. Before setting up our production boxes I read through most of the manual and so fare I have yet to encounter any issue that I could figure out using just the manual.
