+dns:
+  enable: true
+  use-hosts: true
+  ipv6: false
+  enhanced-mode: fake-ip
+  fake-ip-range: 198.18.0.1/16

+  fallback-filter:
+    geoip: false
+    geosite:
+      - gfw  # `geosite` filter only use fallback server to resolve ip, prevent DNS leaks to unsafe DNS providers.

+```yaml
+# Enable the TUN listener
+tun:
+  enable: true
+  stack: lwip # lwip(recommended), system or gvisor
+  dns-listen: 0.0.0.0:53 # additional dns server listen on TUN

+### Script configuration
+Script enables users to programmatically select a policy for the packets with more flexibility.
+
+```yaml

+
+### Proxies configuration
+Support outbound transport protocol `VLESS`.
+
+The XTLS only support TCP transport 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`.
+
+Run Clash by user `clash` as a daemon.
+
+Create the systemd configuration file at /etc/systemd/system/clash.service:
+```
+[Unit]
+Description=Clash daemon, A rule-based proxy in Go.
+After=network.target
+
+[Service]
+Type=simple
+User=clash
+Group=clash
+CapabilityBoundingSet=cap_net_admin
+AmbientCapabilities=cap_net_admin
+Restart=always
+ExecStart=/usr/local/bin/clash -d /etc/clash
+
+[Install]
+WantedBy=multi-user.target
+```
+Launch clashd on system startup with:
+```shell
+$ systemctl enable clash
+```
+Launch clashd immediately with:
+```shell
+$ systemctl start clash
+```
+
+### 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 https://yaling888.github.io/yacd/.
