 In this way you can rest assured that you will never misdirect your links to the
 same subdomain when you meant to change it.
 
+== Use in controllers and views

+You have access to current_subdomain and current_domain methods.

+current_subdomain - returns all subdomains.
+  Example for the URL http://awesome.website.stuff.example.com current_subdomain will return "awesome.website.stuff"
+
+current_domain - returns all subdomains except for the subdomain, including the TLD.
+  Example for the URL http://awesome.website.stuff.example.com current_subdomain will return "website.stuff.example.com"

 == Routing
 
 SubdomainFu can also work within Rails' routing for subdomain-specific routes. For instance, if you only wanted your administrative tools available in the "admin" subdomain you could add this to your routes.rb file:
 
-    map.with_options :conditions => {:subdomain => 'admin} do |admin|
+    map.with_options :conditions => {:subdomain => 'admin'} do |admin|
       admin.resources :posts
       admin.resources :users
     end
+    
+In addition to specifying a string, you could also specify <tt>false</tt> to
+require no subdomain (this includes mirrors that you've set up such as www)
+or a regular expression to match a range of subdomains.
