+# raygui styles
+
+`raygui` comes with **12 custom styles** carefully designed for the best visual experience. Those styles have been created using [rGuiStyler](https://raylibtech.itch.io/rguistyler) tool and they complement internal [default style](default), always available by `raygui`.
+
+## styles usage 
+
+To use those styles with your `raygui` development, you need to call `GuiLoadStyle()` function at initialization, passing the `.rgs` file to load. Note that `.rgs` is by default a binary file containing the style required font data (glyphs data + glyph atlas image data).
+
+Styles can also be embedded in the code if desired, `.h` files are provided with every style containing all the required style data, including the font data. To embed those fonts just add the `.h` to your project and call the required function as specified in the header info.
+
+Here it is a quick overview of those styles, you can navigate to each directory for additional information.
