-## Dashboard
+## Getting Started
+Documentations are now moved to [GitHub Wiki](https://github.com/Dreamacro/clash/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).
+## Advanced usage for this branch
-
+### Build
-## Configration example
+This branch requires cgo and Python3.9, so make sure you set up Python3.9 before building.
-
-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:
 
+For example, build on macOS:
 ```shell
-git clone https://github.com/MetaCubeX/mihomo.git
+brew update
-cd mihomo && go mod download
+brew install python@3.9
-go build
+
+export PKG_CONFIG_PATH=$(find /usr/local/Cellar -name 'pkgconfig' -type d | grep lib/pkgconfig | tr '\n' ':' | sed s/.$//)
+
+git clone -b plus-pro https://github.com/yaling888/clash.git
+cd clash
+
+# build
+make cleancache && make local 
+# or make local-v3
+
+ls bin/
+
+# run
+sudo bin/clash-local
 ```
 
-Set go proxy if a connection to GitHub is not possible:
+### MITM configuration
+A root CA certificate is required, the 
+MITM proxy server will generate a CA certificate file and a CA private key file in your Clash home directory, you can use your own certificate replace it. 
 
-```shell
+Need to install and trust the CA certificate on the client device, open this URL [http://mitm.clash/cert.crt](http://mitm.clash/cert.crt) by the web browser to install the CA certificate, the host name 'mitm.clash' was always been hijacked.
-go env -w GOPROXY=https://goproxy.io,direct
+
+NOTE: this feature cannot work on tls pinning
+
+WARNING: DO NOT USE THIS FEATURE TO BREAK LOCAL LAWS
+

 ```
 
-Build with gvisor tun stack:
+### DNS configuration
+Support resolve ip with a proxy tunnel.
 
-```shell
+Support `geosite` with `fallback-filter`.
-go build -tags with_gvisor
+
+Use `curl -X POST controllerip:port/cache/fakeip/flush` to flush persistence fakeip
+ ```yaml
+ dns:
+   enable: true
+   use-hosts: true
+   ipv6: false
+   enhanced-mode: fake-ip

+     ipcidr:
+       - 0.0.0.0/32
+ ```
+
+### TUN configuration
+Supports macOS, Linux and Windows.
+
+On Windows, you should download the [Wintun](https://www.wintun.net) driver and copy `wintun.dll` into the system32 directory.
+```yaml
+# Enable the TUN listener
+tun:
+  enable: true
+  stack: gvisor # System or gVisor
+  # device: tun://utun8 # or fd://xxx, it's optional
+  dns-hijack: 
+    - 0.0.0.0:53 # hijack all public
+  auto-route: true # auto set global route
+```
+### Rules configuration
+- Support rule `GEOSITE`.
+- Support rule `USER-AGENT`.
+- Support `multiport` condition for rule `SRC-PORT` and `DST-PORT`.
+- Support `network` condition for all rules.
+- Support `process` condition for all rules.
+- Support source IPCIDR condition for all rules, just append to the end.
