 In contrast to the standard Qt docking system, docking with the ADS works more like a drag & drop operation. That means, the dragged dock widget or dock area is not undocked immediately. Instead, a drag preview widget is created and dragged around to indicate the future position of the dock widget or dock area. The actual dock operation is only executed when the mouse button is released. That makes it possible, to cancel an active drag operation with the escape key.
 
 The drag preview widget can be configured by a number of global dock manager flags:
+
 - `DragPreviewIsDynamic`: if this flag is enabled, the preview will be adjusted dynamically to the drop area
 - `DragPreviewShowsContentPixmap`: the created drag preview window shows a static copy of the content of the dock widget / dock are that is dragged
 - `DragPreviewHasWindowFrame`: this flag configures if the drag preview is frameless like a QRubberBand or looks like a real window

+Scrutiny is an [open source](https://github.com/scrutinydebugger/) non-intrusive, real-time debugger for embedded systems, built for fast introspection, memory access, and signal visualization—without stopping your application. It uses the Qt Advanced Docking System (ADS) to provide fully customizable dashboards for monitoring and control.
+
+Some of the highlights are:
+
+- **Debug without interfering** — Inspect C++ memory live without disrupting execution flow.
+- **HIL testing made easy** — Write to variables through the GUI or SDK to simulate conditions.
+- **Configure during production** — Access and tweak variables anytime via GUI or Python.
+- **Catch fast events** — Embedded graphs sample at task-level frequency, even with multithreading.
+- **Build your dashboard** — Use ADS to create and save custom layouts for your debug sessions.
+- **No JTAG needed** — Communicates over serial, CAN, or network interfaces.
+- **Compact C++11 library** — Lightweight and easy to integrate into your firmware.
+- **Live graphs and runtime values** — Visualize variables, RPVs, and aliases in real time.
+
+ADS powers Scrutiny’s flexible interface, letting users organize views and data panels to suit their workflow — ideal for real-time monitoring, testing, and debugging.

+## Using ADS on Linux
+
+### Supported Distributions
+
+Unfortunately, there is no such thing as a Linux operating system. Linux is a heterogeneous environment with a variety of different distributions. So it is not possible to support "Linux" like it is possible for Windows. It is only possible to support and test a small subset of Linux distributions. The library can be compiled for and has been developed and tested with some Linux distributions. Depending on the used window manager or compositor, dock widgets
+with native title bars are supported or not. If native title bars are not supported,
+the library switches to `QWidget` based title bars.

+- **Ubuntu 18.04, 19.10 and 20.04** - native title bars are supported
+- **Ubuntu 22.04** - uses Wayland -> no native title bars
+
+### Requirements 
+
+There are some requirements for the Linux distribution that have to be met:
+
+- an X server that supports ARGB visuals and a compositing window manager. This is required to display the translucent dock overlays ([https://doc.qt.io/qt-5/qwidget.html#creating-translucent-windows](https://doc.qt.io/qt-5/qwidget.html#creating-translucent-windows)). If your Linux distribution does not support this, or if you disable this feature, you will very likely see issue [#95](https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System/issues/95).
+- Wayland is not properly supported by Qt yet. If you use Wayland, then you should set the session type to x11: `XDG_SESSION_TYPE=x11 ./AdvancedDockingSystemDemo`. You will find more details about this in issue [#288](https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System/issues/288).

+### Manjaro xfce 25.0.1 and Xubuntu 24.04.2 issues
+
+There is a known focus stealing issue with the xfce4 compositor reported in issue [#734]. This issue
+can be solved by enabling the setting **Activate focus stealing prevention**. `Settings > Window Manager Tweaks` has a tab called `Focus`.
+
+Selecting `Activate focus stealing prevention` and `Do nothing` for `When a window raises itself`, seems to mitigate the issue. Deselecting `Enable display compositing` on the `Compositor` tab, also works.

+## OpenGl + ADS
+
+If you would like to use OpenGL widgets with ADS such as `GLWidget`, QML or `QWebEngineView`, then you need
+to set `QApplication::setAttribute(Qt::AA_ShareOpenGLContexts)` before creating your application and your
+widgets (see issue [#732])
+
+```c++
+int main(int argc, char *argv[])
+{
+  QApplication::setAttribute(Qt::AA_ShareOpenGLContexts);
+  QApplication application(argc, argv);
+  ...
+}
+```
