-## Why you need Private AdGuard DNS
+### Why you need private AdGuard DNS
 
 Today, you can connect anything to the Internet: TVs, refrigerators, smart bulbs, or speakers. But along with the undeniable conveniences you get trackers and ads. A simple browser-based ad blocker will not protect you in this case, but AdGuard DNS, which you can set up to filter traffic, block content and trackers, has a system-wide effect.
 
-We already have [public AdGuard DNS](../public-dns/overview.md) and [AdGuard Home](https://github.com/AdguardTeam/AdGuardHome). These solutions work fine for some users, but for others, the public AdGuard DNS lacks the flexibility of configuration, while the AdGuard Home lacks simplicity. That's where private AdGuard DNS comes into play. It has the best of both worlds: it offers customizability, control and information - all through a simple easy-to-use dashboard.
