 ## Getting Started
 Documentations are now moved to [GitHub Wiki](https://github.com/Dreamacro/clash/wiki).
 
-## 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) transport by the XRAY-CORE.
-```yaml
-proxies:
-  - name: "vless"
-    type: vless
-    server: server
-    port: 443
-    uuid: uuid
-    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
-    tls: true
-    udp: true
-    network: ws
-    servername: example.com # priority over wss host
-    # skip-cert-verify: true
-    ws-opts:
-      path: /path
-      headers: { Host: example.com, Edge: "12a00c4.fm.huawei.com:82897" }
-
-  - name: "vless-grpc"
-    type: vless
-    server: server
-    port: 443
-    uuid: uuid
-    tls: true
-    udp: true
-    network: grpc
-    servername: example.com # priority over wss host
-    # skip-cert-verify: true
-    grpc-opts: 
-      grpc-service-name: grpcname
-```
-
-### IPTABLES configuration
-Work on Linux OS who's supported `iptables`
-
-```yaml
-# Enable the TPROXY listener
-tproxy-port: 9898
-
-iptables:
-  enable: true # default is false
-  inbound-interface: eth0 # detect the inbound interface, default is 'lo'
-```
-
-
-### General installation guide for Linux  
-+ Create user given name `clash-meta`
-
-+ Download and decompress pre-built binaries from [releases](https://github.com/MetaCubeX/Clash.Meta/releases)  
-
-+ Rename executable file to `Clash-Meta` and move to `/usr/local/bin/` 
-
-+ Create folder `/etc/Clash-Meta/` as working directory 
-
-
-
-Run Meta Kernel by user `clash-meta` as a daemon.
-
-Create the systemd configuration file at `/etc/systemd/system/Clash-Meta.service`:
-
-```
-[Unit]
-Description=Clash-Meta Daemon, Another Clash Kernel.
-After=network.target NetworkManager.service systemd-networkd.service iwd.service
-
-[Service]
-Type=simple
-User=clash-meta
-Group=clash-meta
-LimitNPROC=500
-LimitNOFILE=1000000
-CapabilityBoundingSet=cap_net_admin
-AmbientCapabilities=cap_net_admin
-Restart=always
-ExecStartPre=/usr/bin/sleep 1s
-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).
