+    #Introduction
+\*------------------------------------*/
+/**
+ * The code AND the comments use naming conventions to refer to each part of
+ * the UI put in place by this component. If you see that somewhere they are
+ * not followed please consider a Pull Request. The naming conventions are:
+ *
+ * "Component" : the widget itself as a whole. This is the last time it will be
+ *               called anything different than "component". So, stay away from
+ *               "widget", "button" or anything else when referring to the
+ *               Component in general.
+ *
+ * "Main Button" : the button that is always in view. Hovering or clicking on it
+ *                 will reveal the child buttons.
+ *
+ * "Child buttons" : if you've read the previous point you know what they are.
+ *                   Did you read the previous point? :)
+ *
+ * "Label(s)" : the tooltip that fades in when hovering over a button.
+
+/*------------------------------------*\
+    #SETTINGS | Variables
+\*------------------------------------*/

+ * These variables are the default styles that serve as fallback and can be
+ * easily customised at compile time.
