 ## Advanced usage for this branch
+### DNS configuration
+Support resolve ip with a proxy tunnel.
+
+Support `geosite` with `fallback-filter`.
+```yaml
+dns:
+  enable: true
+  use-hosts: true
+  ipv6: false
+  enhanced-mode: fake-ip
+  fake-ip-range: 198.18.0.1/16
+  listen: 127.0.0.1:6868
+  default-nameserver:
+    - 119.29.29.29
+    - 114.114.114.114
+  nameserver:
+    - https://doh.pub/dns-query
+    - tls://223.5.5.5:853
+  fallback:
+    - 'https://1.0.0.1/dns-query#Proxy'  # append the proxy adapter name to the end of DNS URL with '#' prefix.
+    - 'tls://8.8.4.4:853#Proxy'
+  fallback-filter:
+    geoip: false
+    geosite:
+      - gfw  # `geosite` filter only use fallback server to resolve ip, prevent DNS leaks to unsafe DNS providers.
+    domain:
+      - +.example.com
+    ipcidr:
+      - 0.0.0.0/32
+```
+
 ### TUN configuration
 Supports macOS, Linux and Windows.
