 ## Quick Start
 
-### Initialization
+### Qt Widgets Application
 
-First of all, you're supposed to add the following code in your `main` function in a very early stage (MUST before the construction of any `Q(Gui|Core)Application` objects).
-
+First, setup `WidgetWindowAgent` for your QWidget instance. (Each widget needs its own agent.)
 ```c++
-int main(int argc, char *argv[]) {
-#ifdef Q_OS_WINDOWS
-    QCoreApplication::setAttribute(Qt::AA_DontCreateNativeWidgetSiblings);
-#elif defined(Q_OS_MAC)
-# if QT_VERSION < QT_VERSION_CHECK(6, 0, 0)
-    qputenv("QT_MAC_WANTS_LAYER", "1");
-# endif
-#endif
+auto w = new MyWidget();
+auto agent = new WidgetWindowAgent(w);
+agent->setup(w);
+```
+
+You can also initialize the agent in the widget constructor.
+```c++
+MyWidget::MyWidget(QWidget *parent) {
+    // ...
+    auto agent = new WidgetWindowAgent(w);
+    agent->setup(w);
 }
 ```
 
-### Qt Widgets Application
+Then, construct your title bar widget, without which the window is lacking in basic interaction feature. You can use the [`WindowBar`](examples/shared/widgetframe/windowbar.h) provided by `WidgetFrame` in the examples as the container for your title bar components.
 
-TODO
+Let `WidgetWindowAgent` know which widget the title bar is.
+```c++
+agent->setTitleBarWidget(myTitleBar);
+```
+
+Set system button hints to let `WidgetWindowAgent` know the role of the widgets, which is important for the Snap Layout to work.
+```c++
+agent->setSystemButton(QWK::WindowAgent::Base::Maximize, maxButton);
+```
+
+Set hit-test visible hint to let `WidgetWindowAgent` know the widgets that desire to receive mouse events. 
+```c++
+agent->setHitTestVisible(myTitleBar->menuBar(), true);
+```
+Other region inside the title bar will be regarded as the draggable area for user to move the window.
+
+Check [`MainWindow`](examples/mainwindow/mainwindow.cpp#L108) example to get detailed information.
