 This section will describe **Device Rules** in Cacti.
 
+Cacti Automation relies on create device Rules these rules help the automation process figure out what type of device is being scanned.
+Based on the device rule REGEX the automation engine can apply the appropriate template to the device i.e if there is a REGEX for IOS.
+The automation engine may pick the Cisco router template for the device
+
 ![Automation Device Rules](images/automation-device-templates.png)
+Below you will be able to choose a REGEX that will help identify the device the REGEX can be in any Perl supported format.
+You can select either to match by system description i.e the device hostname or the system name i.e Cisco
+
+An example regex for Cisco would be
+(Cisco Internetwork Operating System Software|IOS)
+This matches based on the system name of the Cisco IOS software
+
+Using this info automation would apply the appropriate device template you choose
+If you see below we match for a system that matches Linux once a device is found with that system name
+it is assigned the Net-SNMP device template.te.

+If the System/Device you are matching has a unique OID you can also match based on that.

 # Automation Discovered Devices
 
-This section will describe **Discovered Devices** in Cacti.
+After you initiate a scan from automation Cacti will compare devices
+found to the device rules and SNMP options you set.
+
+If Cacti is unable to match the device to a device template or unable to
+find a proper SNMP credential.
+
+Also if you have the automatically add to Cacti set to off the devices will
+also be put in this section.
+
+The Discovered Devices section can be found by navigating to the 
+following area.
+
+![Discovered Devices](images/automation-discovered-devices-dropdown.png)

+Below you can see devices that have been found during the scan that did
+not meet a match criteria.
+
+You will see the IP that was scanned as well if avaliable the resolved
+hostname either via DNS or netbios.

+When the user clicks on the Tab an Iframe will display the webpage.
