+Select2
+=======
+
+Select2 is a jQuery-based replacement for select boxes. It supports searching, remote data sets, and infinite scrolling of results.
+
+To get started, checkout examples and documentation at http://ivaynberg.github.com/select2
+
+Use cases
+---------
+
+* Enhancing native selects with search.
+* Enhancing native selects with a better multi-select interface.
+* Loading data from JavaScript: easily load items via ajax and have them searchable.
+* Nesting optgroups: native selects only support one level of nested. Select2 does not have this restriction.
+* Tagging: ability to add new items on the fly.
+* Working with large, remote datasets: ability to partially load a dataset based on the search term.
+* Paging of large datasets: easy support for loading more pages when the results are scrolled to the end.
+* Templating: support for custom rendering of results and selections.
+
+Browser compatibility
+---------------------
+* IE 8+
+* Chrome 8+
+* Firefox 10+
+* Safari 3+
+* Opera 10.6+
+
+Integrations
+------------
+
+* [Wicket-Select2](https://github.com/ivaynberg/wicket-select2) (Java / [Apache Wicket](http://wicket.apache.org))
+* [select2-rails](https://github.com/argerim/select2-rails) (Ruby on Rails)
+* [AngularUI](http://angular-ui.github.com/#directives-select2) ([AngularJS](angularjs.org))
+* [Django](https://github.com/applegrew/django-select2)
+* [Symfony](https://github.com/19Gerhard85/sfSelect2WidgetsPlugin)
+* [Bootstrap](https://github.com/t0m/select2-bootstrap-css) (CSS skin)
+* [Yii](https://github.com/tonybolzan/yii-select2)
+
+Internationalization (i18n)
+---------------------------
+
+Select2 supports multiple languages by simply including the right
+language JS file (`select2_locale_it.js`, `select2_locale_nl.js`, etc.).
+

+it, and make a pull request back to Select2 here on GitHub.
