+The classes *.fade-from-left* and *.fade-from-right* automatically change to *.fade-in* at 600px screen width for better mobile support.
+
+### Element list
+
+The element list is automatically updated on every scroll event. You can disable this to improve performance.
+```js
+VueAnimations.setAutomaticElementListReload(false);
+```
+
+If disabled, the list needs to updated manually, otherwise the animations *will not* work.
+You can do that with the reloadElements function:
+```js
+VueAnimations.reloadElements()
+```
+
+For the best possible performance the list should be updated on every component mount, that implements any animations.
