Extract the package and move it into the Products directory of your Zope installation (remove the '-1.0a1' part of the name in the same time). Now you can install it to your CMF sites using the quick installer or the usual PortalTransforms.Install.install external method.
I'll try to collect some resources here
Please contribute your transformations so we'll be able to provide a great transformations base ! I'll try to make available some developper oriented documentation until the 1.0 final to make that easier. Until that it shouldn't be too hard to write your own transform by looking at the interfaces and at the existant ones ;)Enjoy !
