That does not give a lot of information, to help.
If you mean you don't understand 'entry' means, for example in 'explain how that entry relates to the current situation' or in 'Pick an entry from the Scale-Size table', than I can tell you, you are overthinking it.
I'm not one of the creators, but I'm willing to provide some pointers, if you can specify what you don't understand.
Still, in the ExNovo_1-1.pdf, there is an example starting from page 12. That could give you some pointers.
