 A small patch to Drupal core is required for this module to work. It is included in the package.
 
+A basic setup, for Apache: 
+Ths setup is for when you have one master domain and one or more slave subdomains for the master
+domain, like:
+
+www.domain.com
+sub1.domain.com
+sub2.domain.com
+
+The instructions pertain to setup of Apache and what your sites directory might look like.  Step 2 talks
+about if you are setup for multisites. 
+
+1) You do not need to setup any additional DNS entries, and you only need one settings.php file.
+
+2) If you are running a multisite setup, and your settings.php (you only need one in this basic setup)
+is not in /sites/default/, but rather in /sites/www.domain.com/ then you need a symbolic link that 
+points /sites/default/ to /sites/www.domain.com/ by doing something like:
+ln -s www.domain.com default from within the /sites/ directory assuming /sites/www.domain.com/ already exists.
+
+3) In httpd.conf, you need to have a ServerAlias directive for each slave subdomain within the 
+vitual host entry for the master domain.  This may look something like:
+
+<VirtualHost *>
+   ServerName mainurl.com
+   ServerAlias sub1.mainurl.com
+   ServerAlias sub2.mainurl.com
+# you could also just do ServerAlias *.mainurl.com to match all possible sub domains
+   DocumentRoot /var/www/html
+</VirtualHost>
+
+4) When you change httpd.conf, don't forget to restart apache to have it take affect.
+
+Setup the multidomain and singlesignon modules as explained on their respective settings pages.
