 Securing your online accounts and doing your bit to protect your data is extremely important and increasingly more so as hackers get more sophisticated.
 FIDO's U2F enables you to add a simple unobtrusive method of 2nd factor authentication, allowing users of your service and/or application to link a hardware key to their account.
 
+## Story about this library fork
+
+All started in this [issue](https://github.com/Samyoul/U2F-php-server/issues/8) in October 2020.
+I quickly worked hard on building tests and opening a [pull-request](https://github.com/Samyoul/U2F-php-server/pull/9).
+But nothing got merged because the library author vanished.
+
+### What does change in this fork ?
+
+For the first released version: nothing changed, only tests where written. And PHP 8.1 support was done.
+Future versions may change things.
