+\title Porting Qt5 to Qt6 Guide
+\brief Provides guidance to migrate your Qt 5 application to Qt 6.
+
+Qt 6 is a result of the conscious effort to make this C++ framework more
+efficient and easy to use. This release replaces quite a few legacy APIs with
+more meaningful ones, such as the newer version of Qt Quick.
+
+We try to maintain binary and source compatibility for all the public APIs in
+each release, but some changes were inevitable in an effort to make Qt a
+better framework. In this topic, we try to summarize those changes and
+provide guidance to handle them.
+
+The following list summarizes the changes in Qt 6:
