How do I install eclipse PDE?

I have already installed the eclipse IDE for Java developers (Helios Service Release 2)

How do I now install the Plug-in Developers Environment (PDE) on top of that? I thought that it should be possible to install it from an update site, like any other eclipse plug-in. But I can't find the correct update site anywhere.

What is PDE Eclipse?

The Plug-in Development Environment (PDE) provides tools to create, develop, test, debug, build and deploy Eclipse plug-ins, fragments, features, update sites and RCP products.

How do I download new software for Eclipse?

Go to Help > Install New Software. In the “Work with” field, enter this URL: http://download.eclipse.org/releases/indigo. Click Add. When the plugins are discovered, open the Mobile and Device Development Tools hierarchy and check Mobile Tools for Java Examples and Mobile Tools for Java SDK.

Try that in Eclipse:

Help → Install New Software... → Choose The Eclipse Project Updates in field Work With → Filter for RCP Plug-In

Then press Next and follow the instructions!
