+#Morss - Get ful text RSS feeds
 
 This tool's goal is to get full-text RSS feeds out of striped RSS feeds, commonly available on internet. Indeed most newspapers only make a small description available to users in their rss feeds, which makes the RSS feed rather useless. So this tool intends to fix that problem.
 This tool opens the links from the rss feed, then downloads the full article from the newspaper website and puts it back in the rss feed.
 
-morss also has experimental support for Atom feeds.
+You can use this program online for free at **<http://morss.it/>**.

+##Dependencies

+You do need:
+- [python](http://www.python.org/) >= 2.6
+- [lxml](http://lxml.de/) for xml parsing
+- this [readability](https://github.com/buriy/python-readability) fork
+
+You may also need:
+- Apache, with python-cgi support, to run on a server
+- a fast internet connection

 morss will also try to figure out whether the full content is already in place (for those websites which understood the whole point of RSS feeds). However this detection is very simple, and only works if the actual content is put in the "content" section in the feed and not in the "summary" section.
