 ## 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`.
 
-Restore `Redir remote resolution`.
+Use `curl -X POST controllerip:port/cache/fakeip/flush` to flush persistence fakeip

 ### TUN configuration
+Simply add the following to the main configuration:
 
-Supports macOS, Linux and Windows.
+#### NOTE:
-
+> auto-route and auto-detect-interface only available on macOS, Windows and Linux, receive IPv4 traffic
-Built-in [Wintun](https://www.wintun.net) driver.
 
 ```yaml
-# Enable the TUN listener
 tun:
   enable: true
-  stack: gvisor #  only gvisor
+  stack: system # or gvisor
-  dns-hijack: 
+  # device: tun://utun8 # or fd://xxx, it's optional
-    - 0.0.0.0:53 # additional dns server listen on TUN
+  # 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-providers `RULE-SET`.
+- 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.
