+***A class to make it very easy to deal with database connections.***
 
 This is [__version 4__](https://github.com/ezSQL/ezSQL/tree/v4) that has many modern programming practices in which will break users of version 3.
 
 [__Version 3__](https://github.com/ezSQL/ezSQL/tree/v3) broke version 2.1.7 in one major way, it required *PHP 5.6*. Which drop mysql extension support, other than that, nothing as far using the library was changed, only additional features.
 
-This library has an `Database` class, a combination of the [Factory](https://en.wikipedia.org/wiki/Factory_method_pattern) pattern with an [Dependency Injection](https://en.wikipedia.org/wiki/Dependency_injection) container hosting. The library is following many OOP principles, one in which, properties public access has been removed.
