 #### PHP 5
-I've dropped PHP 5 support in early 2017 already. PHP 5.6 and 7.0 will be retired in the end of 2018, so there's no reason to stay on these versions and you really should upgrade your server.
-However, if upgrading is not an option for you, you can use the unsupported PHP 5.6 backport of the 2.0 branch. It's available as [`1.0.8` on Packagist](https://packagist.org/packages/chillerlan/php-qrcode#1.0.8). Please let PHP 5 die.

-#### Authenticator trait
-This library includes a trait for [chillerlan/php-authenticator](https://github.com/chillerlan/php-authenticator) that allows
-to create `otpauth://` QR Codes for use with mobile authenticators - just add `"chillerlan/php-authenticator": "^2.0"` to the `require` section of your *composer.json*
-```php
-use chillerlan\QRCode\{QRCode, QROptions, Traits\QRAuthenticator};
-
-class MyAuthenticatorClass{
-	use QRAuthenticator;
-
-	public function getQRCode(){
-
-		// data fetched from wherever
