-## 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
+### General configuration
+```yaml
+sniffing: true # Sniff TLS SNI
 
-## Configration example
-
-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:
-
-```shell
-git clone https://github.com/MetaCubeX/mihomo.git
-cd mihomo && go mod download
-go build
+force-cert-verify: true # force verify TLS Certificate, prevent machine-in-the-middle attacks
 ```
 
-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
-go env -w GOPROXY=https://goproxy.io,direct
+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.
+
+NOTE: this feature cannot work on tls pinning
+
+WARNING: DO NOT USE THIS FEATURE TO BREAK LOCAL LAWS
+
+```yaml
+# Port of MITM proxy server on the local end
+mitm-port: 7894
+
+# Man-In-The-Middle attack
+mitm:
+  hosts: # use for others proxy type. E.g: TUN, socks
+    - +.example.com
+  rules: # rewrite rules
+    - '^https?://www\.example\.com/1 url reject' # The "reject" returns HTTP status code 404 with no content.
+    - '^https?://www\.example\.com/2 url reject-200' # The "reject-200" returns HTTP status code 200 with no content.
+    - '^https?://www\.example\.com/3 url reject-img' # The "reject-img" returns HTTP status code 200 with content of 1px png.
+    - '^https?://www\.example\.com/4 url reject-dict' # The "reject-dict" returns HTTP status code 200 with content of empty json object.
+    - '^https?://www\.example\.com/5 url reject-array' # The "reject-array" returns HTTP status code 200 with content of empty json array.
+    - '^https?://www\.example\.com/(6) url 302 https://www.example.com/new-$1'
+    - '^https?://www\.(example)\.com/7 url 307 https://www.$1.com/new-7'
+    - '^https?://www\.example\.com/8 url request-header (\r\n)User-Agent:.+(\r\n) request-header $1User-Agent: haha-wriohoh$2' # The "request-header" works for all the http headers not just one single header, so you can match two or more headers including CRLF in one regular expression.
+    - '^https?://www\.example\.com/9 url request-body "pos_2":\[.*\],"pos_3" request-body "pos_2":[{"xx": "xx"}],"pos_3"'
+    - '^https?://www\.example\.com/10 url response-header (\r\n)Tracecode:.+(\r\n) response-header $1Tracecode: 88888888888$2'
+    - '^https?://www\.example\.com/11 url response-body "errmsg":"ok" response-body "errmsg":"not-ok"'
 ```
 
-Build with gvisor tun stack:
+### DNS configuration
+Support resolve ip with a proxy tunnel.
 
-```shell
-go build -tags with_gvisor
+Support `geosite` with `fallback-filter`.
+
+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
+   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#Proxy'  # append the proxy adapter name to the end of DNS URL with '#' prefix.
+     - 'tls://8.8.4.4:853#Proxy'
+   fallback-filter:
+     geoip: false
+     geosite:
+       - gfw  # `geosite` filter only use fallback server to resolve ip, prevent DNS leaks to untrusted DNS providers.
+     domain:
+       - +.example.com
+     ipcidr:
+       - 0.0.0.0/32
+ ```
+
+### TUN configuration
+Simply add the following to the main configuration:
+
+#### NOTE:
+> auto-route and auto-detect-interface only available on macOS, Windows and Linux, receive IPv4 traffic
+
+```yaml
+tun:
+  enable: true
+  stack: system # or gvisor
+  # device: tun://utun8 # or fd://xxx, it's optional
+  # dns-hijack:
+  #   - 8.8.8.8:53
+  #   - tcp://8.8.8.8:53
+  #   - any:53
+  #   - tcp://any:53
+  auto-route: true # auto set global route
+  auto-detect-interface: true # conflict with interface-name
+```
+or
+```yaml
+interface-name: en0
+
+tun:
+  enable: true
+  stack: system # or gvisor
+  # dns-hijack:
+  #   - 8.8.8.8:53
+  #   - tcp://8.8.8.8:53
+  auto-route: true # auto set global route
+```
+It's recommended to use fake-ip mode for the DNS server.
+
+Clash needs elevated permission to create TUN device:
+```sh
+$ sudo ./clash
+```
+Then manually create the default route and DNS server. If your device already has some TUN device, Clash TUN might not work. In this case, fake-ip-filter may helpful.
+
+Enjoy! :)
+
+#### For Windows:
+```yaml
+tun:
+  enable: true
+  stack: gvisor # or system
+  dns-hijack:
+    - 198.18.0.2:53 # when `fake-ip-range` is 198.18.0.1/16, should hijack 198.18.0.2:53
+  auto-route: true # auto set global route for Windows
+  # It is recommended to use `interface-name`
+  auto-detect-interface: true # auto detect interface, conflict with `interface-name`
+```
+Finally, open the Clash
+
+### 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.
