Allowing our users to annotate your webpage is easy. First you'll need to download the source code (or you can use our hosted version) and include it on your page along with jQuery. Then simply add the following lines to load the Annotator, allowing users with AnnotateIt accounts to start annotating immediately:


For full details, see the Getting Started page on the Annotator wiki.

If you want more control, or you don't want your users (who might already have accounts on your website) to need accounts here at AnnotateIt, we provide support for delegated authentication: you control who gets to annotate, and AnnotateIt will store annotations for you and your users.

             .annotator('setupPlugins', {
               tokenUrl: ''
