+ * This component works just like a switch statement, although the conditions of the first items
+ * are checked first, and the first component with a condition that is true will be shown.
+ *
+ * For single conditions and options any kind of component can be taken, while the Option-component
+ * is dedicated for this job. The only important thing is that this component has to have a condition property.
+ *
+ * You should also give a default option with a condition that always evaluates to true.
+ *
+ * A quick example would be some content that is only to be shown when the user is logged in:
+ *
+ * function SomeRestrictedContent(props) {
+ * const { isSignedIn } = props;
+ *
+ * return (
+ *
+ *
+ *
+ *
+ * );
+ * }
+ *
+ * In the example you'll have to note that the default option is at the bottom of all the options
+ * since it would always be taken otherwise (the options' conditions are checked from top to bottom)
