+    \ingroup qtquickcontrols2-indicators
+    \brief Indicates background activity, for example, while content is being loaded.
+
+    \image qtquickcontrols2-busyindicator.gif
+
+    The busy indicator should be used to indicate activity while content is
+    being loaded or the UI is blocked waiting for a resource to become available.
+
+    The following snippet shows how to use the BusyIndicator:
+
+    \qml
+    BusyIndicator {
+        running: image.status === Image.Loading
+    }
+    \endqml
+
+    BusyIndicator is similar to an indeterminate \l ProgressBar. Both can be
+    used to indicate background activity. The main difference is visual, and
+    that ProgressBar can also present a concrete amount of progress (when it
+    can be determined). Due to the visual difference, busy indicators and
+    indeterminate progress bars fit different places in user interfaces.
+    Typical places for a busy indicator:
+    \list
+    \li in the corner of a \l ToolBar
+    \li as an overlay on top of a \l Page
+    \li on the side of an \l ItemDelegate
+    \endlist
