How to install Web Platform Tools in Eclipse?

Question

Which URL do I install this and any pre-reqs from, and how can I install them? Been struggling with this for the last 1 hour with no luck.

new 2013 answer: it seems to depend on what version of eclipse you're running.

1. click "help" -> "about eclipse sdk" to find the version (e.g. 4.2.2).
2. optionally, from the version number you can know the codename (e.g. Juno) from wikipedia: http://en.wikipedia.org/wiki/Eclipse_%28software%29#Releases
3. go here: http://wiki.eclipse.org/WTP_FAQ#How_do_I_install_WTP.3F
4. right click on the correct WTP link copy the link address (e.g. WTP 3.4) (they should be listed by version and codename)
5. now in eclipse, click "help" -> "install new software..." and paste the link location in the "work with" field (e.g. "http://download.eclipse.org/webtools/repository/juno/").
6. choose "Web Tools Platform (WTP #.#.#)" and click next and install everything.
7. restart eclipse, close all open files and re-open them for web tools to start working.
