 \paragraph{Actual loading and configuration}
 We load the font using freeType, after checking if it was loaded correctly we set size of a single character, disable byte-alignment in order for the text to be rendered correctly, preload first 128 [ASCII] characters and since we already loaded everything we wanted we destroy FreeType library

+\paragraph{Loading characters}
+In order to preload ASCII characters we use a method loadCharacter from TextRenderer, it uses FreeType library to load character, then generates textures for a character (it needs to allign a texture to character), sets options for texture and adds the character object to characters array

 \subsection{Dependency Management}
 There are several libraries: OpenGL, GLFW, stb\_image and freetype being integrated into engine, they are simply included at the top of any files that need them.
