 ## Best Practices
 
 - Give the Pi a static IP or DHCP reservation before installing Pi-hole
-- Use Pi-hole as primary DNS, add a public resolver as secondary
+- Use Pi-hole as primary DNS; for redundancy, add a second Pi-hole instead of a
+  public resolver if you need strict blocking
 - Enable DoH (DNS-over-HTTPS) with cloudflared for encrypted upstream queries
 - Set `home.lan` as your local domain and create DNS records for all your services
 - Review the Query Log occasionally — blocked queries show you what devices are doing
