 ## Dependencies
 
-Some plugins and CSS components depend on other plugins. If you include plugins individually, make sure to check for these dependencies in the docs. Also note that **all plugins depend on jQuery** (this means jQuery must be included **before** the plugin files). [Consult our `bower.json`]({{ site.repo }}/blob/v{{ site.current_version }}/bower.json) to see which versions of jQuery are supported.
