Hey Guys, I use Adobe InDesign for this job. Great and easy to create a default template. And after edit, you just need export a PDF .
I made a Illustrator template which I base all my pdf help files off of.
I use photoshop and then i add those images to acrobat reader and save it as .pdf You have alot of control with photoshop, maybe you can use that
Myself used to do PDFs (in indesign) and tutorials, now I do just video tutorials as it is time consuming to do both. Here is a screenshoot of how the help file looked:
It is only up to you how much creativity and functionality (or not) you want to “invest” in the help file, I see it as a “bussines card” for my clients ( used to).
PS: the text is blured for obvious reasons
