 ## Advanced usage for this branch
-### General configuration
-```yaml
-sniffing: true # Sniff TLS SNI
-
-force-cert-verify: true # force verify TLS Certificate, prevent machine-in-the-middle attacks
-```
-
-### 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. 
-
-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

 ### DNS configuration
-Support resolve ip with a proxy tunnel or interface.
 
 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

-     - tls://223.5.5.5:853
-   fallback:
-     - 'tls://8.8.4.4:853#proxy or interface'
-     - 'https://1.0.0.1/dns-query#Proxy'  # append the proxy adapter name to the end of DNS URL with '#' prefix.
-   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
+Supports macOS, Linux and Windows.
+
+Built-in [Wintun](https://www.wintun.net) driver.
 
 ```yaml
+# Enable the TUN listener
 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
+  stack: gvisor #  only gvisor
+  dns-hijack: 
+    - 0.0.0.0:53 # additional dns server listen on TUN
   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 rule-providers `RULE-SET`.
 - Support `multiport` condition for rule `SRC-PORT` and `DST-PORT`.
 - Support `network` condition for all rules.

 ### Proxies configuration
-Support outbound protocol `VLESS`.
 
-Support `Trojan` with XTLS.
+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 relay `UDP` traffic.
+Support `Policy Group Filter`
 
-Support filtering proxy providers in proxy groups.
-
-Support custom http request header, prefix name and V2Ray subscription URL in proxy providers.
