 # ValiWork - validation framework

 ValiWork is a validation framework that provides sane API and ability to write own validators that returns arbitrary things. It is goroutine-safe and fast.

 Default validators will return ``error``.
 
+*There are no default validators ATM. Feel free to submit PR with them!*
+
 ## Validators registering and namespacing
 
 Default validators using "T_N" scheme, where ``T`` is data type (string, int, int64, etc.) and ``N`` is a validator name (which can be a generic string). Please, use same naming scheme. Example good validators names:
