 ## 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`.

+## Dashboard
 
-## Build
+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).
 
-You should install [golang](https://go.dev) first.
+## Configration example
 
-Then get the source code of Clash.Meta:

+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:
 
 ```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

-### 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).
