Unlike dead frog points where insulated rail gaps are not normally essential, live frog points and associated track do require a bit of forethought before finally pinning everything down. Much of the wiring illustrated in the commercial instruction books may be eliminated quite simply by the use of strategically-placed insulated single rail gaps, without losing any of the operational functionality.
Once again it is much easier to understand the principals of wiring using live frog points by looking at the diagrams. Remember that with live frog points the frog is permanently connected to its adjacent running rails at all times, therefore the polarity of these rails is dependent on the setting of the point, not on whether it is the furthest or nearest away rail. The diagrams will explain this much more simply than text ever can. Don't despair, keep it live.
