 ## Development
 
+### Cargo build feature for SELinux
+
+If your target system uses SELinux, you will want to enable the 'selinux' feature when building the innernet binary.
+This will ensure that innernet maintains the correct selinux context on the /etc/hosts file when adding hosts.  To do so add ```--features selinux``` to the ```cargo build``` options.
+The `selinux-devel` package will need to be installed for the correct headers.
