+\section1 Writing a qmltypes file
+
+QML modules may refer to one or more type information files in their
+\l{Writing a qmldir file}{qmldir} file. These usually have the .qmltypes
+extension and are read by external tools to gain information about
+types defined in plugins.
+
+As such qmltypes files have no effect on the functionality of a QML module.
+Their only use is to allow tools such as Qt Creator to provide code completion,
+error checking and other functionality to users of your module.
+
+Any module that uses plugins should also ship a type description file.
+
+The best way to create a qmltypes file for your module is to generate it
+using the \c qmlplugindump tool that is provided with Qt.
+
+Example:
+If your module is in \c /tmp/imports/My/Module, you could run
+\code
+qmlplugindump My.Module 1.0 /tmp/imports > /tmp/imports/My/Module/mymodule.qmltypes
+\endcode
+to generate type information for your module. Afterwards, add the line
+\code
+typeinfo mymodule.qmltypes
+\endcode
+to \c /tmp/imports/My/Module/qmldir to register it.
+
+While the qmldump tool covers most cases, it does not work if:
+\list
+\o The plugin uses a \l{QDeclarativeCustomParser}. The component that uses
+   the custom parser will not get its members documented.
+\o The plugin can not be loaded. In particular if you cross-compiled
+   the plugin for a different architecture, qmldump will not be able to
+   load it.
+\endlist
+
+In case you have to create a qmltypes file manually or need to adjust
+an existing one, this is the file format:
+
+\qml
+import QtQuick.tooling 1.0
+
+// There always is a single Module object that contains all
+// Component objects.
+Module {
+    // A Component object directly corresponds to a type exported
+    // in a plugin with a call to qmlRegisterType.
+    Component {
+
+        // The name is a unique identifier used to refer to this type.
+        // It is recommended you simply use the C++ type name.
+        name: "QDeclarativeAbstractAnimation"
+
+        // The name of the prototype Component.
+        prototype: "QObject"
+
+        // The name of the default property.
+        defaultProperty: "animations"
+
+        // The name of the type containing attached properties
+        // and methods.
+        attachedType: "QDeclarativeAnimationAttached"
+
+        // The list of exports determines how a type can be imported.
+        // Each string has the format "URI/Name version" and matches the
+        // arguments to qmlRegisterType. Usually types are only exported
+        // once, if at all.
+        // If the "URI/" part of the string is missing that means the
+        // type should be put into the package defined by the URI the
+        // module was imported with.
+        // For example if this module was imported with 'import Foo 4.8'
+        // the Animation object would be found in the package Foo and
+        // QtQuick.
+        exports: [
+            "Animation 4.7",
+            "QtQuick/Animation 1.0"
+        ]
+
+        Property {
+            name: "animations";
+            type: "QDeclarativeAbstractAnimation"
+            // defaults to false, whether this property is read only
+            isReadonly: true
+            // defaults to false, whether the type of this property was a pointer in C++
+            isPointer: true
+            // defaults to false: whether the type actually is a QDeclarativeListProperty<type>
+            isList: true
+        }
+        Property { name: "loops"; type: "int" }
+        Property { name: "name"; type: "string" }
+        Property { name: "loopsEnum"; type: "Loops" }
+
+        Enum {

+            values: {
+                "Infinite": -2,
+                "OnceOnly": 1
+            }
+        }
+
+        // Signal and Method work the same way. The inner Parameter
+        // declarations also support the isReadonly, isPointer and isList
