Better readme / example code

[uragecz]

Right now, it's almost impossible to use this library even for simple forms.. For example i am trying to use simple select.. where i have defined options.. But i can' get it work / don't know how to add those options.. Also would be great to see example for some simple validations.. Like this i will spend more time discovering how to do it, than just writing it..

Also trying to use pattern with custom error message.. but don't know how i should add it.. Or required with custom err message
