+Integrate OpenIPC into HomeKit
+---
+
+Currently OpenIPC doesn't have native HomeKit support yet, integration is made by 3rd party package [go2rtc](https://github.com/AlexxIT/go2rtc "go2rtc"), thanks [@gtxaspec](https://github.com/gtxaspec "@gtxaspec") for adding this package into OpenIPC
+
+### Hardware requirement
+
+Since the compiled binary file will 3.3MB in size, flash chip size should be 16MB  at least, DDR size should be 128MB at least
+
+### Compile go2rtc package
+
+Install go and upx first
+```
+apt update
+apt install golang upx
+```
+- ####  Method 1: Compile the whole firmware
+Edit board config file in `firmware/br-ext-chip-xxxx/configs` directory, add the following line to enable the go2rtc package
+```
+BR2_PACKAGE_GO2RTC=y
+```
+then run
+```
+make distclean
+make all BOARD=board_config_name
+```
+- #### Method2: Compile the package only
+```
+make distclean
+make br-go2rtc-rebuild BOARD=board_config_name
+```
+The compiled go2rtc binary file will located at `firmware/output/per-package/go2rtc/target/usr/bin`, default config file at `firmware/output/per-package/go2rtc/target/etc`
+
+### Edit config file
+
+Put config file `go2rtc.yaml` into `/etc/` directory, example config:
+
+```
+log:
+  level: info  # default level
+  api: trace
+  exec: debug
+  ngrok: info
+  rtsp: warn
+  streams: error
+  webrtc: fatal
+
+rtsp:
+  listen: ":8553"
+
+webrtc:
+  candidates:
+    - stun:8555
+
+streams:
+  openipc: rtsp://admin:12345@127.0.0.1/stream=0
+
+homekit:
+  openipc:                   # same stream ID from streams list
+    pin: 19550224           # custom PIN, default: 19550224
+    name: openipc-ssc30kq      # custom camera name, default: generated from stream ID
+    device_id: openipc       # custom ID, default: generated from stream ID
+```
+
+### Run go2rtc
+
+```
+/usr/bin/go2rtc -config /etc/go2rtc.yaml &
+```
+
+Open the Home app on your Apple device, click the `+` button on the top-right corner, the OpenIPC camera should appear there automatically, enter the pin numbers in the config file to pair with it.
+
+### Autorun on startup
+
+Add the following lines into /etc/rc.local
+
+```
+/usr/bin/go2rtc -config /etc/go2rtc.yaml &
+```
+
+### Limitations
+
+- No HomeKit Secure Video support yet
+- No motion sensor support yet
+- No two-way audio support yet
+
