+ * Slides can be customized quite a bit to create very unique slides.
+ * But exposing all the of the option underneath can make slides overwhelming.
+ * So Ionic only exposes the most common properties. If there is a property that
+ * you would like to customize though, you can change it's value like so.
+ *
+ * ```ts
+ * export class MySlides {
+ *   @ViewChild(Slides) slider: Slides;
+ *   ngAfterViewInit() {
+ *     this.slider.freeMode = true;
+ *   }
+ * }
+ *
+ * ```
+ *
+ * To see all the options, look at the [source for slides](https://github.com/driftyco/ionic/blob/master/src/components/slides/slides.ts#L144)
+ *
  * @demo /docs/v2/demos/src/slides/
