 The top-level ``CMakeLists.txt`` file for a project must contain a
 literal, direct call to the :command:`project` command; loading one
 through the :command:`include` command is not sufficient.  If no such
-call exists CMake will implicitly add one to the top that enables the
-default languages (``C`` and ``CXX``).
+call exists, CMake will issue a warning and pretend there is a
+``project(Project)`` at the top to enable the default languages
+(``C`` and ``CXX``).
 
 .. note::
-  Call the :command:`cmake_minimum_required` command at the beginning
-  of the top-level ``CMakeLists.txt`` file even before calling the
-  :command:`project()` command.  It is important to establish version and
-  policy settings before invoking other commands whose behavior they
-  may affect.  See also policy :policy:`CMP0000`.
