+# Multi Site
+
+[![Build Status](https://secure.travis-ci.org/radiant/radiant-multi-site-extension.png?branch=master)](http://travis-ci.org/radiant/radiant-multi-site-extension)
+
+Created by Sean Cribbs, November 2007. Inspired by the original virtual_domain behavior.
+
+Multi Site allows you to host multiple websites on a single Radiant installation.
+
+Each site has its own independent sitemap/page-tree and these attributes:
+
+  name: Whatever you want to call the site
+  domain: A Ruby regular expression (without the //) to match the request against
+  base_domain: A canonical domain name for doing quicker matches and for generating absolute URLs against
+  homepage_id: The numerical database ID of the root page (usually you can just leave this alone).
+
+Included images are slightly modified from FamFamFam Silk Icons by Mark James:

+

+## Other Extensions
+
+Multi Site allows you to customize routes within your other extensions. To restrict a route to a particular site, pass the site's name into the conditions hash:
+
+    map.resources :things, :conditions => { :site => 'My Site' }
+
+You can also scope a route to multiple sites with an array:
+
+    map.resources :things, :conditions => { :site => ['My Site', 'Your Site'] }
+
