This describes how to install the software from the eclipsefp project. (You can install either the Haskell or the OCaml support separately, or both.)

Start Eclipse and choose from the menu Help > Software Updates > Find and Install. Select 'Search for new features to install', hit 'Next'. Press 'Add update site', enter whatever you like as 'Name' and http://eclipsefp.sf.net/updates as 'URL'. Press 'OK', check the checkbox and hit 'Next'. From here it should be self-explaining :-)

Note: if you access the internet though a proxy server (this is the case in many organisations) then you must tell Eclipse about the proxy: Window > Preferences > Install/Update.

Alternatively, you can download the entire update site for every release from the sourceforge file release site. Start Eclipse and choose from the menu Help > Software Updates > Find and Install. Select 'Search for new features to install', hit 'Next'. Press 'Add archived site' and browse to the downloaded file. Press 'OK', check the checkbox and hit 'Next'. From here it should be self-explaining :-)
