guide families of revit

[Marcusbox]

in revit every family has its rules. Where the hell are they written?
Is there an online guide section explaining the secrets of each family? ? ?
otherwise could you tell me tutorials or manuals? (I have already looked at that in the tutorial section)

Thanks, bye.

for the specification of families, there are manuals until the 2010 version
