 Thank you for considering contributing to TGUI!
 
-All contributions are highly appreciated, whether they are code patches, bug reports or suggestions. Note that while reported bugs are usually handled very quickly, suggestions can sometimes take a long time to be implemented due to TGUI being developed in the spare time of a single developer with only occational code contributions by others.

 ## Style guide
 
-TGUI has no official style guide yet, but since it's style was heavily influenced by SFML code, the [SFML code style guide](https://www.sfml-dev.org/style.php) mostly matches with TGUI code.

 There are 3 differences that I'm aware of:
-- TGUI uses `@` in doxygen documentation where SFML uses `\`
-- Lines consisting of only shashes (to separate functions) are longer in TGUI
-- TGUI code targets c++14

 TGUI - Texus' Graphical User Interface
 =======================================
 
-TGUI is a cross-platform modern c++ GUI library.  
+TGUI is a cross-platform modern C++ GUI library.
 Although originally a library for SFML, it now also has backends for SDL, GLFW and raylib.
