+Code style configuration
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+Developers must follow the project's :ref:`code style <doc_code_style_guidelines>`
+and IDE should help them to do it. By default, Qt Creator does use spaces for indentation
+which is incorrect for Godot project. You can change this behavior by
+changing the "Code Style" in *Options* -> *C++*.

+Click on *Edit* to change the current settings, then click on *Copy Built-in Code Style* button
+to set a new code style. Set a name for it (e.g. Godot) and change the Tab policy
+to be *Tabs Only*.
