-.. warning::
-    PlatformIO generates empty project by default and **code auto-completion
-    will not work!** To enable auto-completion please choose one of:
-
-    * Add source files ``*.c, *.cpp, etc`` to ``src`` directory and re-initialize
-      project with command above
-    * Manually correct ``add_executable`` command in ``CMakeLists.txt`` file
-      (will be created in project directory after initialization).
-
-    ``*.ino`` file isn't acceptable for ``add_executable`` command. You should
-    convert it manually to ``*.cpp``. See `project example <https://github.com/platformio/platformio-examples/tree/develop/ide/clion>`_.
