+## Advanced usage for this branch
+
+### DNS configuration
+
+Support `geosite` with `fallback-filter`.
+
+Restore `Redir remote resolution`.
+
+Support resolve ip with a `Proxy Tunnel`.
+
+```yaml
+proxy-groups:
+
+  - name: DNS
+    type: url-test
+    use:
+      - HK
+    url: http://cp.cloudflare.com
+    interval: 180
+    lazy: true
+```
+```yaml
+dns:
+  enable: true
+  use-hosts: true
+  ipv6: false
+  enhanced-mode: redir-host
+  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#DNS'  # append the proxy adapter name or group name to the end of DNS URL with '#' prefix.
+    - 'tls://8.8.4.4:853#DNS'
+  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.
+
+Built-in [Wintun](https://www.wintun.net) driver.
+
+```yaml
+# Enable the TUN listener
+tun:
+  enable: true
+  stack: gvisor #  only gvisor
+  dns-hijack: 
+    - 0.0.0.0:53 # additional dns server listen on TUN
+  auto-route: true # auto set global route
+```
+### Rules configuration
+- Support rule `GEOSITE`.
+- Support rule-providers `RULE-SET`.
+- Support `multiport` condition for rule `SRC-PORT` and `DST-PORT`.
+- Support `network` condition for all rules.
+- Support source IPCIDR condition for all rules, just append to the end.
+- The `GEOSITE` databases via https://github.com/Loyalsoldier/v2ray-rules-dat.
+```yaml
+rules:
+
+  # network(tcp/udp) condition for all rules
+  - DOMAIN-SUFFIX,bilibili.com,DIRECT,tcp
+  - DOMAIN-SUFFIX,bilibili.com,REJECT,udp
+    
+  # multiport condition for rules SRC-PORT and DST-PORT
+  - DST-PORT,123/136/137-139,DIRECT,udp
+  
+  # rule GEOSITE
+  - GEOSITE,category-ads-all,REJECT
+  - GEOSITE,icloud@cn,DIRECT
+  - GEOSITE,apple@cn,DIRECT
+  - GEOSITE,apple-cn,DIRECT
+  - GEOSITE,microsoft@cn,DIRECT
+  - GEOSITE,facebook,PROXY
+  - GEOSITE,youtube,PROXY
+  - GEOSITE,geolocation-cn,DIRECT
+  - GEOSITE,geolocation-!cn,PROXY
+    
+  # source IPCIDR condition for all rules in gateway proxy
+  #- GEOSITE,geolocation-!cn,REJECT,192.168.1.88/32,192.168.1.99/32
+
+  - GEOIP,telegram,PROXY,no-resolve
+  - GEOIP,private,DIRECT,no-resolve
+  - GEOIP,cn,DIRECT
+  
+  - MATCH,PROXY
+```
+
+
+### Proxies configuration
+
+Active health detection `urltest / fallback` (based on tcp handshake, multiple failures within a limited time will actively trigger health detection to use the node)
+
+Support `Policy Group Filter`
+
+```yaml
+proxy-groups:
+
+  - name: 🚀 HK Group
+    type: select
+    use:
+      - ALL
+    filter: 'HK'
+
+  - name: 🚀 US Group
+    type: select
+    use:
+      - ALL
+    filter: 'US'
+
+proxy-providers:
+  ALL:
+    type: http
+    url: "xxxxx"
+    interval: 3600
+    path: "xxxxx"
+    health-check:
+      enable: true
+      interval: 600
+      url: http://www.gstatic.com/generate_204
+
+```
+
+
+
+Support outbound transport protocol `VLESS`.
+
+The XTLS support TCP/UDP by the XRAY-CORE.
+```yaml
+proxies:
+  - name: "vless-tcp"
+    type: vless
+    server: server
+    port: 443
+    uuid: uuid
+    network: tcp
+    servername: example.com # AKA SNI
+    # flow: xtls-rprx-direct # xtls-rprx-origin  # enable XTLS
+    # skip-cert-verify: true
+    
+  - name: "vless-ws"
+    type: vless
+    server: server
+    port: 443
+    uuid: uuid
+    udp: true
+    network: ws
+    servername: example.com # priority over wss host
+    # skip-cert-verify: true
+    ws-path: /path
+    ws-headers:
+      Host: example.com
+```
+
+### IPTABLES auto-configuration
+Only work on Linux OS who support `iptables`, Clash will auto-configuration iptables for tproxy listener when `tproxy-port` value isn't zero.
+
+If `TPROXY` is enabled, the `TUN` must be disabled.
+```yaml
+# Enable the TPROXY listener
+tproxy-port: 9898
+# Disable the TUN listener
+tun:
+  enable: false
+```
+Create user given name `Clash.Meta`.
+
+Run Meta Kernel by user `Clash.Meta` as a daemon.
+
+Create the systemd configuration file at /etc/systemd/system/clash.service:
+
+```
+[Unit]
+Description=Clash.Meta Daemon, Another Clash Kernel.
+After=network.target
+
+[Service]
+Type=simple
+User=Clash.Meta
+Group=Clash.Meta
+CapabilityBoundingSet=cap_net_admin
+AmbientCapabilities=cap_net_admin
+Restart=always
+ExecStart=/usr/local/bin/Clash.Meta -d /etc/Clash.Meta
+
+[Install]
+WantedBy=multi-user.target
+```
+Launch clashd on system startup with:
+```shell
+$ systemctl enable Clash.Meta
+```
+Launch clashd immediately with:
+
+```shell
+$ systemctl start Clash.Meta
+```
+
+### Display Process name
+
+Clash add field `Process` to `Metadata` and prepare to get process name for Restful API `GET /connections`.
+
+To display process name in GUI please use [Dashboard For Meta](https://github.com/Clash-Mini/Dashboard).
