Installation

Unpack the archive with all contained directory information into your Zope products directory (lib/python/Products). This should give you a directory "FrameTitle". Restart Zope; FrameTitle should show up now in your products overview

Deinstallation

If you really dislike FrameTitle and want to get rid of it, just delete its directory, or at least its contained __init__.py file (and its compiled versions with the .pyc and possibly .pyo extensions), and restart Zope. Now your Zope looks like it had looked ever before. But you don't want that, really...
