+    \class QtConcurrent::QTaskBuilder
+    \inmodule QtConcurrent
+    \brief The QTaskBuilder class is used for adjusting task parameters.
+    \since 6.0
+
+    \ingroup thread
+
+    It's not possible to create an object of this class manually. See
+    \l {Concurrent Task} for more details and usage examples.

+
+/*!
+    \fn template <class Task, class ...Args> [[nodiscard]] QFuture<InvokeResultType> QtConcurrent::QTaskBuilder<Task, Args...>::spawn()
+
+    Runs the task in a separate thread and returns a future object immediately.
+    This is a non-blocking call. The task might not start immediately.
+*/
+
+/*!
+    \fn template <class Task, class ...Args> template <class ...ExtraArgs> [[nodiscard]] QTaskBuilder<Task, ExtraArgs...> QtConcurrent::QTaskBuilder<Task, Args...>::withArguments(ExtraArgs &&...args)
+
+    Sets the arguments \a args the task will be invoked with. The code is ill-formed
+    (causes compilation errors) if:
+    \list
+        \li This function is invoked more than once.
+        \li The arguments count is zero.
+    \endlist

+/*!
+    \fn template <class Task, class ...Args> [[nodiscard]] QTaskBuilder<Task, Args...> &QtConcurrent::QTaskBuilder<Task, Args...>::withPriority(int newPriority)

+
+/*!
+    \typedef InvokeResultType
+    \relates QtConcurrent::QTaskBuilder
+
+    The simplified definition of this type looks like this:
+    \code
+    template <class Task, class ...Args>
+    using InvokeResultType = std::invoke_result_t<std::decay_t<Task>, std::decay_t<Args>...>;
+    \endcode
+
+    The real implementation also contains a compile-time check for
+    whether the task can be invoked with the specified arguments or not.
