+### 14.04.5.5 ISO image built on 2017/11/26
+
+**Please note!** This ISO image includes the **EXPERIMENTAL** Elastic stack!
+
+The Elastic components are included in the ISO image and Setup gives you an option of Stable Setup (ELSA) or Experimental Setup (Elastic).  If you do not want to try the new Elastic stack, you can choose Stable Setup.  
+
+If you **do** want to proceed with the new 14.04.5.5 ISO image, please skip down to the "Download and Verify" section.  If you would prefer an ISO image with no Elastic components at all, you have a few options:
+
+- Use the older Security Onion 14.04.5.2 ISO image (and then run `sudo soup`):<br>
+https://github.com/Security-Onion-Solutions/security-onion/blob/master/old/Verify_ISO_14.04.5.2.md
+
+OR 
+
+- Install your preferred flavor of Ubuntu 14.04 and then add our PPA and packages:<br>

+
+Import the signing key:  
+```
+gpg --import KEYS
+```
+
+Download the signature file for the ISO:  
+```
+wget https://github.com/Security-Onion-Solutions/security-onion/raw/master/sigs/securityonion-14.04.5.5.iso.sig
+```
+
+Download the ISO image:

+
+Verify the downloaded ISO image using the signature file:  
+```
+gpg --verify securityonion-14.04.5.5.iso.sig securityonion-14.04.5.5.iso
