-From the `doc` location run:
+Ensure that `pdflatex` is on your PATH, test with:
+
+pdflatex --help

+
+Then create the latex build from the `doc` location:
+

+Once done do:
 
+cd build/latex
+make
 
-sphinx-build -b pdf src .
 
+If there any warnings then hit return to pass through them to continue building ( also decide if you need to fix them or not ).
 
-This will then generate a single PDF for all of the documentation within `doc`.
+Now you should have Ghostscript.pdf ready within `build/latex`.
 
+Move the Ghostscript.pdf file into the root of "doc" and replace the existing PDF as required.
