     \section1 The Code
 
+    We first define a \c commandLineUrlArgument function that returns the URL to open.
+    This is either the first positional argument given on the command line, or
+    \c https://www.qt.io as a fallback.

+    \printto int main
+
     In the \c main function we first set the Qt::AA_EnableHighDpiScaling.
     This lets the web view automatically scale on high-dpi displays.
 
     Next, we instantiate a QApplication and a QWebEngineView. The URL
-    to load is taken from the command-line in \c commandLineUrlArgument and
+    to load is taken from \c commandLineUrlArgument and
     loaded by calling \l QWebEngineView::setUrl. The view widget is
     given a reasonable default size, and shown.
     Finally, QApplication::exec() launches the main event loop.
