 ## Objective
-amalgame provides a web-based interactive platform for creating, analyzing and evaluating vocabulary alignments.  It aims to support domain experts to make alignments interactively.  To realize this it focuses on simple alignment techniques which the user understand and knows how to use, and which are sufficiently fast to be used in an interactive session.  amalgame keeps track of all the provenance related information, so that mapping experiments can be replicated later, and other users can explore the context that played a role in creating the mappings.  amalgame is implemented by using common web technology on the client (e.g. HTML,CSS,AJAX and the YUI toolkit) and SWI-Prolog's ClioPatria platform on the server.

 ## Installation
 Amalgame is a web application build as a package in the ClioPatria semantic web server. To install, make sure you have:
 
-1. The latest development release of SWI Prolog, see http://www.swi-prolog.org/Download.html
+1. The latest development release of SWI Prolog, at least version 7.1.x. See http://www.swi-prolog.org/Download.html
 2. ClioPatria itself, see http://cliopatria.swi-prolog.org/help/Download.html
 3. Once you have your ClioPatria server up and running, just install amalgame as a cpack:
