 If you want to use your own variables for the gravity script (i.e. storing the files in a different location) and don't want to have to change them every time there is an update to the script, create a file called `/etc/pihole/pihole.conf`. In it, you should add your own variables in a similar fashion as shown below:
 
 ```
-origin=/var/run/pihole
+piholeDir=/var/run/pihole
 adList=/etc/dnsmasq.d/adList
 ```
