 It is however recommended to use native **Frame Processor Plugins** for processing, as those are much faster than JavaScript and can sometimes operate with the GPU buffer directly.
 You can simply pass a `Frame` to a native Frame Processor Plugin directly.
 
+## Advanced Frame Handling in C++
+
+**vision-camera** is built using prefabs, which allow you to easily extend the library with your own native code.
+you can link it in your `CMakeLists.txt` like this:
+
+```make
+find_package(react-native-vision-camera REQUIRED CONFIG)
+# ...
+target_link_libraries(
+  ${PACKAGE_NAME}
+  # ... other libs
+  react-native-vision-camera::VisionCamera
+)
+```
+
+then pass a `jsi::Object` to your C++ code. and then use the `FrameHostObject` to access the frame data:
+
+```cpp
+ #include "frameprocessor/FrameHostObject.h"
+
+# in your jsi::Function
+jni::global_ref <JFrame> unwrappedFrame = frame->frame;
+auto frameWidth = unwrappedFrame->getWidth();
+__android_log_print(ANDROID_LOG_DEBUG, "VisionCamera",
+                    "frame width: %d", frameWidth);
+auto frameHeight = unwrappedFrame->getHeight();
+__android_log_print(ANDROID_LOG_DEBUG, "VisionCamera",
+                    "frame height: %d", frameHeight);
+```
