+<h2>Connecting to the Database</h2>
+
 <p>Once your database has been created, you may also need to
 edit your pg_hba.conf file in order to grant the application
 access to the database as the 'general' user.</p>
 
+<p>In a simple installation, where you do not have untrusted
+users on your database server, and your database is on the same
+computer as the web server, the following line (near the top
+of the pg_hba.conf file) should be enough:</p>
+
+<pre>
+local   rscds    general   trust
+</pre>
+
+<p>This means that anyone on the local computer (including the
+web application) will have rights to connect to the RSCDS
+database as the 'general' user.  It will not allow remote access,
+or access as any user other than 'general'.</p>
+
+<p>If you want greater security, or if you want to have the
+database on a different server, you should read the
+<a href="http://www.postgresql.org/docs/8.1/interactive/client-authentication.html">PostgreSQL documentation on pg_hba.conf</a>
+for the version you are using.</p>
