Understanding Nengo Parameters

I used the Nengo convertor to convert a fully connected ANN to SNN (LIF activation).

I have a set of parameters including weight matrcies, max_rates = 1, encoders = -1/1, scaled_encoders=1/-1, intercept = -0. What do these values mean?

Also, how do these terms correspond to the LIF working mechanism?
What would be the values of membrane threshold and reset mechanism (zero/subtract) for my case?
