 ## 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:
+```sh
+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 local
+# or make local-v3
+
+ls bin/
+
+# run
+sudo bin/clash-local
