+    \contentspage QDoc Manual
+
+    \title Example Manifest Files
+
+    QDoc generates XML files that contain information about all documented
+    examples and demos. These files, named \c {examples-manifest.xml} and
+    \c {demos-manifest.xml}, are used by Qt Creator to present a list of
+    examples in its welcome screen and to link to their documentation.
+
+    \section1 Manifest XML Structure
+
+    A manifest file has the following structure:
+
+    \code
+    <?xml version="1.0" encoding="UTF-8"?>
+    <instructionals module="QtGui">
+        <examples>
+            <example
+                name="Analog Clock Window Example"
+                docUrl="qthelp://org.qt-project.qtgui.502/qtgui/analogclock.html"
+                projectPath="gui/analogclock/analogclock.pro"
+                imageUrl="qthelp://org.qt-project.qtgui.502/qtgui/images/analogclock-window-example.png">
+                <description><![CDATA[The Analog Clock Window example shows how
+                    to draw the contents of a custom window.]]></description>
+                <tags>analog,clock,window</tags>
+                <fileToOpen>gui/analogclock/main.cpp</fileToOpen>
+            </example>
+            ...
+        </examples>
+    </instructionals>
+    \endcode
+
+    Each \c {<example>} element contains information about a name,
+    description, the location of the project file and documentation,
+    as well as a list of tags associated with the example.
+
+    \target metacontent
+    \section1 Manifest Meta Content
+
+    It is possible to augment the manifest files with additional
+    meta-content - that is, extra attributes and tags for selected
+    examples, using the \c manifestmeta configuration command.
+
+    One use case for meta-content is highlighting a number of prominent
+    examples. Another is improving search functionality by adding
+    relevant keywords as tags for a certain category of examples.
+
+    The examples for which meta-content is applied to is specified using
+    one or more filters. Matching examples to filters is done based on
+    names, with each example name prefixed with a module name and a
+    slash. Simple wildcard matching is supported; by using \c {*} at the
+    end it's possible to match multiple examples with a single string.
+
+    Example:
+
+    \code
+    manifestmeta.filters                = highlighted sql webkit global
+
+    manifestmeta.highlighted.names      = "QtGui/Analog Clock Window Example" \
+                                          "QtWidgets/Analog Clock Example"
+    manifestmeta.highlighted.attributes = isHighlighted:true
+
+    manifestmeta.sql.names              = "QtSql/*"
+    manifestmeta.sql.tags               = database,sql
+
+    manifestmeta.webkit.names           = "QtWebKitExamples/*"
+    manifestmeta.webkit.tags            = webkit
+
+    manifestmeta.global.names           = *
+    manifestmeta.global.tags            = qt5
+    \endcode
+
+    Above, an \c isHighlighted attribute is added to two examples. If
+    the attribute value is omitted, QDoc uses the string \c {true} by
+    default. Extra tags are added for Qt WebKit and Qt SQL examples, and
+    another tag is applied to all examples by using just \c {*} as the
+    match string.
