 The Pi-hole is an **advertising-aware DNS/Web server**. If an ad domain is queried, a small Web page or GIF is delivered in place of the advertisement.
 
-### Gravity
+### Gravity: Finding Ads To Block
+
+The [gravity.sh](https://github.com/pi-hole/pi-hole/blob/master/gravity.sh) script does most of the magic. The script pulls in over 100,000 known ad-serving domains from many sources and aggregates them into a single list.
 
-The [gravity.sh](https://github.com/pi-hole/pi-hole/blob/master/gravity.sh) does most of the magic. The script pulls in ad domains from many sources and compiles them into a single list of [over 1.6 million entries](http://jacobsalmela.com/block-millions-ads-network-wide-with-a-raspberry-pi-hole-2-0) (if you decide to use the [mahakala list](https://github.com/pi-hole/pi-hole/commit/963eacfe0537a7abddf30441c754c67ca1e40965)). This script is controlled by the `pihole` command. Please run `pihole -h` to see what commands can be run via `pihole`.
+#### Additional Blocklists
+You can also use Pi-hole to block additional domains beyond the defaults.  It can even be used to block malware or phising domains.  [The Big Blocklist Collection](https://wally3k.github.io/) is a good resource for finding additional domains to block.
