-Qt Quick Controls 2
-===================
+# Qt Quick Controls 2
 
-![Qt Quick Controls 2 Styles](https://doc.qt.io/qt-5/images/qtquickcontrols2-styles.png)
+**The Qt Quick Controls 2 module has been moved into qtdeclarative.git.**
 
-The Qt Quick Controls 2 module delivers the next generation user interface
-controls based on Qt Quick. In comparison to the desktop-oriented Qt Quick
-Controls 1, Qt Quick Controls 2 are an order of magnitude simpler, lighter and
-faster, and are primarily targeted towards embedded and mobile platforms.
+## Why?
 
-Qt Quick Controls 2 are based on a flexible template system that enables rapid
-development of entire custom styles and user experiences. Qt Quick Controls 2
-comes with a selection of built-in styles:
+The motivation for the move is explained here:
 
-- Default style - a simple and minimal all-round style that offers the maximum performance
-- Fusion style - a platform-agnostic style that offers a desktop-oriented look and feel
-- Imagine style - a designer-friendly style based on image assets
-- Material style - a style based on the Google Material Design Guidelines
-- Universal style - a style based on the Microsoft Universal Design Guidelines
-- Windows style - a style that looks native on Windows
-- macOS style - a style that looks native on macOS
