     Normally, variables are used to contain whitespace-separated lists
     of values. However, it is sometimes necessary to specify values containing
-    spaces. These must be quoted in the following way:
+    spaces. These must be quoted by using the
+    \l{qmake Function Reference#quote-string}{quote()} function in the following way:
 
     \snippet doc/src/snippets/qmake/quoting.pro 0
 
     The quoted text is treated as a single item in the list of values held by
-    the variable. This approach is used to deal with paths that contain spaces,
-    particularly on the Windows platform. See the documentation for the
+    the variable. A similar approach is used to deal with paths that contain
+    spaces, particularly when defining the
     \l{qmake Variable Reference#INCLUDEPATH}{INCLUDEPATH} and
-    \l{qmake Variable Reference#LIBS}{LIBS} variables for examples.
+    \l{qmake Variable Reference#LIBS}{LIBS} variables for the Windows platform.
+    In cases like these, the \l{qmake Function Reference#quote(string)}{quote()}
+    function can be used in the following way:

+    \snippet doc/src/snippets/qmake/spaces.pro quoting include paths with spaces
