Hi Diego,

Thanks for the post. You'll need to do a couple things to get jQuery running:

1. Get the version of jQuery you're looking to use from their website.
2. Create a 'web' directory next to your 'views' directory and place jQuery there (e.g. ../externalModules/helloworld/web/jquery-x.xx.js).
3. Next to your helloWorld.html, create the helloWorld.view.xml (you may have already done this) adding a "dependencies" section. Here's a brief example:

<view xmlns="http://labkey.org/data/xml/view" title="Hello, World!">
      <dependencies>
            <dependency path="jquery-x.xx.js"></dependency>
      </dependencies>
</view>

Here is a more complete write-up on this topic:
