 # Installation
 
 Installation is easy as UI Bootstrap has minimal dependencies - only the AngularJS and Twitter Bootstrap's CSS are required.

+*Notes:*
 * Since version 0.13.0, UI Bootstrap depends on [ngAnimate](https://docs.angularjs.org/api/ngAnimate) for transitions and animations, such as the accordion, carousel, etc. Include `ngAnimate` in the module dependencies for your app in order to enable animation.
 * UI Bootstrap depends on [ngTouch](https://docs.angularjs.org/api/ngTouch) for swipe actions. Include `ngTouch` in the module dependencies for your app in order to enable swiping.

 Be sure to have a loader able to process `css` files like `css-loader`.
 
+If you would prefer not to load your css through your JavaScript file loader/bundler, you can choose to import the `index-nocss.js` file instead, which is available for the modules:
+* carousel
+* datepicker
+* datepickerPopup
+* position
+* timepicker
+* tooltip
+* typeahead

+The other modules, such as `accordion` in the example below, do not have CSS resources to load, so you should continue to import them as normal:
