Documents - Manuals

Hello experts,
Is there any user manuals which can be downloaded for all (user, admin, developer), apart from online?
If yes, please share me the links.
By the way the version am using 7.1

The documentation is available online. There is no direct way to get all the documentation into PDF or something like that.
Yet you can try WEBSITE GRABBER tools like we have in IDM or in any other downloaders.
Hope this will help.
