+
+    \l{Qt for MCUs} enables you to use subsets of QML and Qt Quick Controls
+    types to create UIs for devices that are powered by microcontroller units
+    (MCU). The subset of supported types depends on the Qt for MCUs version
+    that you use for development. In this manual, we indicate which components
+    are supported at the time of writing, but you should always check the
+    \l{Qt for MCUs - All QML Types}{listing of supported QML types} for the
+    latest state.
+
+    To develop for MCUs, \l{Using Project Wizards}{create an MCU project}.
+    Only a subset of properties is supported for the supported types. The
+    properties that are not available on MCUs are marked in the
+    \uicontrol Properties view by enclosing them in square brackets.
