 All new code must follow the following coding guidelines.  
 If you make changes in a file that still uses another coding style, make sure that you follow these guidelines for your changes instead.  
-**Note:** I will now take your head if you forget and use another style. However, most probably the request will be delayed until you fix your coding style.
+**Note 1:** I will not take your head if you forget and use another style. However, most probably the request will be delayed until you fix your coding style.
+**Note 2:** You can use the `uncrustify` program/tool to clean up any source file. Use it with the `uncrustify.cfg` configuration file found in the root folder.
+**Note 3:** There is also a style for QtCreator but it doesn't cover all cases. In QtCreator `Tools->Options...->C++->Code Style->Import...` and choose the `codingStyleQtCreator.xml` file found in the root folder.
