Roughly there are two types of PDF documents, one is a converted document from MS Word, Pages, InDesign or another programme using any (integrated) PDF converter ('save as'). The other type is a scanned document. Your best chance of converting a PDF to a usable word is from the first type. As a rule of thumb, the more complex the original formatting, the more any converter will struggle deciphering it. However, in the second type of document where the PDF is a scanned document and in effect just like an image file, creating a workable conversion that resembles the original will in general be less successful.
The easiest way to turn a pdf into a guide is copy paste from a wordprocessing program file such as MS Word ('.doc'). The quickest route therefore is to turn a PDF into a .doc or .docx file. There are several options, such as using Adobe, MS Word, or One Drive.
Now that you have your content in Word, follow the steps as described in 'From Word'. to create your guide.
TIP: Save the images in your recently converted Doc separately as a JPEG or so you crop them to size or add them as banner.
