I'm not sure what purpose the prologue or epilogue would serve. Is the prologue an introduction? Does it contain facts pertinent to the material that will later be introduced? If so, should this material really be included in the relevant chapters? Or is the prologue about how you came to write the book and the process of writing it? this would probably not be necessary and (although I would be interested) might not be of interest to anyone but other writers, unless you've lived an extraordinarily adventurous life, which you are now writing about. Would the prologue detail your experience and education that qualify you to write the book? I would think this would be better placed in an author bio.
And I can't think what role an epilogue would play in a non-fiction book, but I write knitting books, so I may be overlooking something obvious.
The bottom line, of course, is that if you really don't expect any one to read this material if you call it "prologue" and "epilogue" and you want them to be read, call them something else. Like "first chapter" and "last chapter."
