 =============================
-## Suported RFCs ##
-This library aims to support:
+With the help of
 
-RFC 5321, 5322, 6530, 6531, 6532.
-
-## Requirements ##
-
- * [Composer](https://getcomposer.org) is required for installation
- * [Spoofchecking](https://github.com/egulias/EmailValidator/blob/master/EmailValidator/Validation/SpoofCheckValidation.php) and [DNSCheckValidation](https://github.com/egulias/EmailValidator/blob/master/EmailValidator/Validation/DNSCheckValidation.php) validation requires that your PHP system has the [PHP Internationalization Libraries](https://php.net/manual/en/book.intl.php) (also known as PHP Intl)
-
-## Installation ##
+![Powered by PhpStorm](https://www.jetbrains.com/phpstorm/documentation/docs/logo_phpstorm.png)
+##Installation##
 
 Run the command below to install via Composer
 
 ```shell
-composer require egulias/email-validator "~2.1"
+composer require egulias/email-validator "~1.2"
 ```
 
-## Getting Started ##
-`EmailValidator`requires you to decide which (or combination of them) validation/s strategy/ies you'd like to follow for each [validation](#available-validations).
+##Usage##
 
-A basic example with the RFC validation
-```php
-<?php
-
-use Egulias\EmailValidator\EmailValidator;
-use Egulias\EmailValidator\Validation\RFCValidation;
-
-$validator = new EmailValidator();
-$validator->isValid("example@example.com", new RFCValidation()); //true
-```
-
-
-### Available validations ###
-
-1. [RFCValidation](https://github.com/egulias/EmailValidator/blob/master/EmailValidator/Validation/RFCValidation.php)
-2. [NoRFCWarningsValidation](https://github.com/egulias/EmailValidator/blob/master/EmailValidator/Validation/NoRFCWarningsValidation.php)
-3. [DNSCheckValidation](https://github.com/egulias/EmailValidator/blob/master/EmailValidator/Validation/DNSCheckValidation.php)
-4. [SpoofCheckValidation](https://github.com/egulias/EmailValidator/blob/master/EmailValidator/Validation/SpoofCheckValidation.php)
-5. [MultipleValidationWithAnd](https://github.com/egulias/EmailValidator/blob/master/EmailValidator/Validation/MultipleValidationWithAnd.php)
-6. [Your own validation](#how-to-extend)
-
-`MultipleValidationWithAnd`
-
-It is a validation that operates over other validations performing a logical and (&&) over the result of each validation.
+Simple example:
 
 ```php
 <?php
 
 use Egulias\EmailValidator\EmailValidator;
-use Egulias\EmailValidator\Validation\DNSCheckValidation;
-use Egulias\EmailValidator\Validation\MultipleValidationWithAnd;
-use Egulias\EmailValidator\Validation\RFCValidation;
 
-$validator = new EmailValidator();
-$multipleValidations = new MultipleValidationWithAnd([
-    new RFCValidation(),
-    new DNSCheckValidation()
-]);
-$validator->isValid("example@example.com", $multipleValidations); //true
+$validator = new EmailValidator;
+if ($validator->isValid($email)) {
+	echo $email . ' is a valid email address';
+}
 ```
 
-### How to extend ###
+More advanced example (returns detailed diagnostic error codes):
 
-It's easy! You just need to implement [EmailValidation](https://github.com/egulias/EmailValidator/blob/master/EmailValidator/Validation/EmailValidation.php) and you can use your own validation.
+```php
+<?php
 
+use Egulias\EmailValidator\EmailValidator;
 
-## Other Contributors ##
-(You can find current contributors [here](https://github.com/egulias/EmailValidator/graphs/contributors))
+$validator = new EmailValidator;
+$email = 'dominic@sayers.cc';
+$result = $validator->isValid($email);
 
-As this is a port from another library and work, here are other people related to the previous one:
+if ($result) {
+	echo $email . ' is a valid email address';
+} else if ($validator->hasWarnings()) {
+	echo 'Warning! ' . $email . ' has unusual/deprecated features (result code ' . var_export($validator->getWarnings(), true) . ')';
+} else {
+	echo $email . ' is not a valid email address (result code ' . $validator->getError() . ')';
+}
+```
