 Macros 1.1 custom derive to simplify struct validation inspired by [marshmallow](http://marshmallow.readthedocs.io/en/latest/) and
 [Django validators](https://docs.djangoproject.com/en/1.10/ref/validators/).
-It currently only works on nightly as it uses 2 features: `proc_macro` and `attr_literals`. `proc_macro` should be stable in Rust 1.15 but there are no plans for `attr_literals` yet.
+It relies on the `proc_macro` feature which will be stable in Rust 1.15.
+
+By default all args to a `validate` must be strings if you are using stable. 
+However, if you are using nightly, you can also activate the `attr_literals` feature to be able to use int, float and boolean as well.
+
 
 A short example:
 ```rust
-#![feature(proc_macro, attr_literals)]
-
 #[macro_use] extern crate validator_derive;
 extern crate validator;
 #[macro_use] extern crate serde_derive;

 The `validator` crate can also be used without the custom derive as it exposes all the
