How do I use angular.js with jsdt-jquery?

In What is the best IDE for AngularJS? Tonte Pouncil mentioned that it's possible to add angular.js as a library in jsdt-jquery. How does one go about doing this? thanks!

eclipse
eclipse-plugin
angularjs
jsdt

Actually it is possible to add libraries to JSDT as well. I am not aware of such libraries. But there is angularjs-eclipse Eclipse plugin, see https://github.com/angelozerr/angularjs-eclipse

If you install https://github.com/angelozerr/angularjs-eclipse, you will benefit from

AngularjS features, in other words completion, hyperlink in HTML editor and Javascript editor.
jQuery completion because AngularJS Eclipse is based on the Javascript Inference engine tern.js.
