+### Code style
+
+If you plan to manipulate the code then you'll have to do it by following a [specific code style](https://gist.github.com/federicoiosue/dee53e882b3c70d544f8608769eb02fc).
+Also pay attention if you're using any plugin that automatically formats/cleans/rearrange your code and set it to only change that code that you touched and not the whole files.
+
 ### Test your code contributions!
 
 All code changes and additions **must** be tested.
