 ## Features
 
 - Local HTTP/HTTPS/SOCKS server with authentication support
-- VMess, VLESS, Shadowsocks, Trojan, Snell, TUIC, Hysteria protocol support
+- VMess, Shadowsocks, Trojan, Snell protocol support for remote connections
 - Built-in DNS server that aims to minimize DNS pollution attack impact, supports DoH/DoT upstream and fake IP.
 - Rules based off domains, GEOIP, IPCIDR or Process to forward packets to different nodes
-- Remote groups allow users to implement powerful rules. Supports automatic fallback, load balancing or auto select node
-  based off latency
-- Remote providers, allowing users to get node lists remotely instead of hard-coding in config
-- Netfilter TCP redirecting. Deploy Mihomo on your Internet gateway with `iptables`.
+- Remote groups allow users to implement powerful rules. Supports automatic fallback, load balancing or auto select node based off latency

-## Dashboard
+## Wiki
+Configuration examples can be found at [/docs/config.yaml](https://github.com/MetaCubeX/Clash.Meta/blob/Alpha/docs/config.yaml), while documentation can be found [Clash.Meta Wiki](https://clash-meta.wiki).
 
-A web dashboard with first-class support for this project has been created; it can be checked out at [metacubexd](https://github.com/MetaCubeX/metacubexd).
+## Build
 
-## Configration example
+You should install [golang](https://go.dev) first.
 
-Configuration example is located at [/docs/config.yaml](https://github.com/MetaCubeX/mihomo/blob/Alpha/docs/config.yaml).
-
-## Docs
-
-Documentation can be found in [mihomo Docs](https://wiki.metacubex.one/).
-
-## For development
-
-Requirements:
-[Go 1.20 or newer](https://go.dev/dl/)
-
-Build mihomo:
+Then get the source code of Clash.Meta:
 
 ```shell
-git clone https://github.com/MetaCubeX/mihomo.git
-cd mihomo && go mod download
-go build
+git clone https://github.com/MetaCubeX/Clash.Meta.git
+cd Clash.Meta && go mod download
 ```
 
-Set go proxy if a connection to GitHub is not possible:
+If you can't visit github,you should set proxy first:
 
 ```shell
 go env -w GOPROXY=https://goproxy.io,direct
 ```
 
-Build with gvisor tun stack:
+Now you can build it:
+
+```shell
+go build
+```
+
+If you need gvisor for tun stack, build with:
 
 ```shell
 go build -tags with_gvisor
 ```
 
+<!-- ## Advanced usage of this fork -->
+
+<!-- ### 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

+  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:

+  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: system #   system/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

+### 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`:
+

+
+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 [Razord-meta](https://github.com/MetaCubeX/Razord-meta).
+
+### Dashboard
+
+We also made a custom fork of yacd provide better support for this project, check it out at [Yacd-meta](https://github.com/MetaCubeX/Yacd-meta)

+## Development
