 Requirements
 ------------
 
-This module requires the lastest version of the current Drupal CVS version and
-a working Crontab.
+This module has been tested with Drupal 4.6.x. Earlier and later versions
+may also work. 
+
+A working Crontab is also required. More information on configuration cron is
+available here:
+http://drupal.org/node/23714
 
 Installation
 ------------
 
 1. Create the SQL tables. This depends a little on your system, but the most
    common method is:
-     mysql -u username -ppassword drupal < notify.mysql
+     For MySQL:
+     mysql -u username -p password drupal < notify.sql
+
+     For PostgreSQL:    
+     psql -Uusername drupal <notify.sql 
 
 2. Create a subdirectory 'notify' in the Drupal modules/ directory.
    Copy the notify.module and the notify.inc to that directory.
