 ## Apparmor (Ubuntu LTS)
 
 * Ubuntu uses AppArmor by default - you will most likely run into file access issues without exemptions

+## Secure your Server
 
 * Glass runs on web port 3000 - if you're going to run this on a production server, make sure that you lock it down from the outside world if anyone can access it. Even if they don't have a password - vulnerabilities can surface at any point in the future and your system becomes a prime target

 ## Building dhcpd-pools (Optional)
 
 * Glass uses dhcpd-pools for shared network / subnet utilization and it is bundled by default (For Ubuntu and Debian) when you install. However, if you need to build the binary yourself on another distribution, use the following to build dhcpd-pools and it needs to be placed in the ./bin directory of glass
+* Below shows use of apt-get of unzip/libtool - you will have to use your respective package management system to pull pre-requisites down
