+### Notes for AdGuard Home users
+
+1. In the `config.json`, you may want to add an entry for your non-cached DNS upstreams. You can input this in `ip.adguardhome_upstream` as an array.
+2. Once you have ran the script, you can point the upstream list to the text file generated. For example: `upstream_dns_file: "/root/cache-domains/scripts/output/adguardhome/cache-domains.txt"`
