 ## Features
 
 - Local HTTP/HTTPS/SOCKS server with authentication support
-- VMess, Shadowsocks, Trojan, Snell protocol support for remote connections
+- VMess, VLESS, Shadowsocks, Trojan, Snell, TUIC, Hysteria protocol support
 - 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 hardcoding in config
-- Netfilter TCP redirecting. Deploy Clash 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
+- 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`.
 - Comprehensive HTTP RESTful API controller
 
-## Getting Started
-Documentations are now moved to [GitHub Wiki](https://github.com/Dreamacro/clash/wiki).
+## Dashboard
 
-## Advanced usage for this branch
+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/Clash.Meta.git
-cd Clash.Meta && go mod download
+git clone https://github.com/MetaCubeX/mihomo.git
+cd mihomo && go mod download
+go build
 ```
 
-If you can't visit github,you should set proxy first:
+Set go proxy if a connection to GitHub is not possible:
+
 ```shell
 go env -w GOPROXY=https://goproxy.io,direct
 ```
 
-So now you can build it:
+Build with gvisor tun stack:
+
 ```shell
-go build
-```
-
-### 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

-
-  # network(tcp/udp) condition for all rules
-  - DOMAIN-SUFFIX,bilibili.com,DIRECT,tcp

-
-
-### 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

+## Debugging
 
-### 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 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/MetaCubeX/clash-dashboard).

-## Development
-
-If you want to build an application that uses clash as a library, check out the
-the [GitHub Wiki](https://github.com/Dreamacro/clash/wiki/use-clash-as-a-library)
+Check [wiki](https://wiki.metacubex.one/api/#debug) to get an instruction on using debug
+API.
