+## Intro

+Hackage: [validate-input](http://hackage.haskell.org/package/validate-input)
+Stackage: [validate-input](https://www.stackage.org/package/validate-input)
+
+Input validation combinator library
+
+
+## Library Usage Example
+
+```haskell
+{-# LANGUAGE OverloadedStrings #-}
+{-# LANGUAGE QuasiQuotes #-}
+import Data.Validator
+import qualified Data.Text as T
+
+data Example
+   = Example
+   { ex_username :: T.Text
+   , ex_dogs :: Int
+   } deriving (Show)
+
+main :: IO ()
+main =
+    do putStrLn "Check results:"
+       print example
+
+checkUsername :: Monad m => ValidationRuleT String m T.Text
+checkUsername =
+    lengthBetween 3 12 "Should between 3 and 12 chars"
+    >=> matchesRegex [re|^[A-za-z0-9]+$|] "only alpha num"
+
+checkNumber :: Monad m => ValidationRuleT String m Int
+checkNumber =
+    smallerThan 5 "No more than 5 dogs allowed"
+
+checkExample :: Monad m => ValidationRuleT String m Example
+checkExample e =
+    Example <$> checkUsername (ex_username e)
+            <*> checkNumber (ex_dogs e)
+
+example :: Either String Example
+example =
+    runValidator checkExample $
+    Example
+    { ex_username = "alex"
+    , ex_dogs = 23
+    }
+
+```
