 Installation guide
 
-The following notes apply to pre-alpha releases. Some manual installation is required at this time. 
+The following notes apply to alpha/beta releases. Some manual installation is 
+required at this time. 
 
 
 1. Requirements
-	- Apache with mod-rewrite enabled and "Options All" so you can use a local .htaccess file
-	- PHP > 5.1. The later the better. You'll need 5.3 for full openssl encryption support
-	- PHP command line access with register_argc_argv set to true in the php.ini file
+	- Apache with mod-rewrite enabled and "Options All" so you can use a 
+local .htaccess file
+	- PHP > 5.1. The later the better. You'll need 5.3 for full openssl 
+encryption support
+	- PHP *command line* access with register_argc_argv set to true in the 
+php.ini file
 	- Mysql 5.x
+	- cron
+	
+	[Dreamhost.com offers all of the necessary hosting features at a 
+reasonable price. If your hosting provider doesn't allow Unix shell access, 
+you might have trouble getting everything to work.] 
 
 2. Edit htconfig.php and change system settings. Rename to .htconfig.php
 
 3. Import database.sql into your database with mysql command line or via phpmyadmin
 
-4. Import updates.sql to catch any late-breaking devel changes
+4. Import updates.sql (if it exists) to catch any late-breaking devel changes
 
 5. Put this directory into the root of your web server document area.
 	- To use a subdir of your main site, set the 
 	config variable $a->path to the relative subdir
-	For example to use http://example.com/test - 
+	in .htconfig.php - for example to use http://example.com/test - 
 	set $a->path to 'test'.
+	- Everything will work much better if you can dedicate a domain 
+	or subdomain so that you don't require an extra server path. 
 
 6. Navigate to your site with a web browser and register an account.
 
+7. Set up a cron task to run "php include/poller.php http://my.domain.name" once every 5-10 minutes.
