+Firstly, the LineEditExtension class is registered with the QML system as an extension of QLineEdit:
 
 \snippet referenceexamples/extended/main.cpp 0
 
-The QML engine instantiates a \l QLineEdit
+The QML engine then instantiates a \l QLineEdit:
 
 \snippet referenceexamples/extended/main.cpp 1
 
-and sets a property that oly exists on the extension type.
+In QML, a property is set on the line edit that only exists in the LineEditExtension class:

-The QML engine instantiates a \l QLineEdit and sets a property that
-only exists on the extension type. The extension type performs calls on the
