 Introduction
 ============
 
-This project is python port of Validator.js which is a library for string validation. 
+This project is inspired from Validator.js which is a library for string validation. 
 So people who are familiar with Validator.js can easily switch to this library.
 
-It is also a good way to learn how to port a library from one language to another. 
-I have tried to keep the code as similar as possible to the original library. 
-if you find any bugs or have any suggestions please open an issue. 
-if you want to contribute please open a pull request.
