What is better than a [Pi-hole](https://github.com/pi-hole/pi-hole) blocking trackers, advertisements, and other malicious domains on your network? That's right, **two** Pi-hole blocking all that junk on your network!
- [Seriously. Why two Pi-hole?](https://github.com/vmstan/gravity-sync/wiki/Frequent-Questions#why-do-i-need-more-than-one-pi-hole)
But if you have more than one Pi-hole in your network you'll want a simple way to keep the list configurations and local DNS settings identical between the two. That's where Gravity Sync comes in. With proper preparation, it should only take a few minutes to install. Ideally you setup Gravity Sync and forget about it -- and in the long term, it would be awesome if the Pi-hole team made this entire script unnecessary.
Gravity Sync is not developed by or affiliated with the Pi-hole project. This is project an unofficial, community effort, that seeks to implement replication (which is currently not a part of the core Pi-hole product) in a way that provides stability and value to Pi-hole users. The code has been tested across multiple user environments but there always is an element of risk involved with running any arbitrary software you find on the Internet.
