Custom arguments seems to be missing from the docs

I was browsing the new docs; it seems the following is missing in the Vue example and isn't stated anymore in the docs:
https://github.com/robsontenorio/vue-api-query/blob/master/tests/dummy/models/User.js

Maybe I'm browsing the wrong section(s)? Is it also possible to have some sort of `setter` in the model? :)

Thanks.
