[Bit-dev] BIT 1.4.1-1: Ignorant new user: Where is Help file for backintime-qt?

I'm going to be asking a lot of dumb questions to help me make my install of BIT of greater value - so your patience will be most appreciated. The first is to ask where I can find the help file for backintime-qt and how would I install it on a Ubuntu-based distro? The response to clicking on the Help menu and then selecting Help (F1) is to be informed I'm looking at the Help pages for the command line version of backintime, not the GUI version (which I am using). Clearly, somehow, I have messed up the install. I installed BIT using my package manager (Synaptic).
