+///
+/// To use SDL_ttf functions, SDL_ttf library must be initialized first.
+/// This initialization and automatic deinitialization is handled by
+/// this class. You may only use SDL_ttf (Font class) functionality
+/// while SDLTTF object lives. SDL itself must not be initialized to use
+/// TTF
+///
+/// Usage example:
+/// \code
+/// int main() {
+///     SDL2pp::SDLTTF ttf;
+///
+///     // ...use SDL_ttf functions...
+///
+///     // SDL_ttf library is automatically deinitialized before exit
+///     return 0;
+/// }
+/// \endcode
