 ## Advanced usage for this branch
+### Build
+This branch requires cgo and Python3.9, so make sure you set up Python3.9 before building.
+
+For example, build on macOS:
+```shell
+brew update
+brew install python@3.9
+
+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
+```
+
+### 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
+
+```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/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"'
+```
 
 ### DNS configuration
+Support resolve ip with a proxy tunnel.
 
 Support `geosite` with `fallback-filter`.
 
-Restore `Redir remote resolution`.
+Use `curl -X POST controllerip:port/cache/fakeip/flush` to flush persistence fakeip
-
+ ```yaml
-Support resolve ip with a `Proxy Tunnel`.
+ dns:

 # Enable the TUN listener
 tun:
   enable: true
