     as this will improve the procedure of reproducing your problem and
     allow the developers to address the issue in a more efficient way.

     This example shows how to enable text translation in QML.

+
+    \section1 Introduction
+
+    The QML runtime automatically loads a translation from the i18n subdirectory
+    of the root QML file, based on the system language. The translations are
+    held in QM files that must be generated from TS files.
+
+    \section1 Updating Translations
+
+    The \c{.ts} files are created and updated by running:
+
+    \code
+    lupdate i18n.qml -ts i18n/base.ts
+    \endcode
+
+    If no translation file exists, one will be created. If a file already exists,
+    it will be updated to contain the latest strings from the QML file.
+
+    Translations for new languages are created by copying \c{i18n/base.ts} to
+    \c{i18n/qml_<lang>.ts} The TS files can then be edited with
+    \l{Qt Linguist Manual}{Qt Linguist}:
+
+    \code
+    linguist i18n/qml_fr.ts
+    \endcode
+
+    The run-time translation files are then generated by running:
+
+    \code
+    lrelease i18n/*.ts
+    \endcode
