+For use in **Browsers**, `Human` library includes pre-bundled `CPU`, `WASM` and `WebGL` backends,  
+there is no need to load them externally  
+
+For use in **NodeJS**, `Human` library supports `tfjs-node` and `tfjs-node-gpu` implementations of `tensorflow` backend  
+which have to be loaded before `Human` library  
+
+Experimental support is added for `WebGPU` backend in **Browsers** and `WASM` backend in **NodeJS**

+## Tensorflow Backend
+
+When used in `NodeJS`, load either `tfjs-node` or `tfjs-node-gpu` modules before loading `Human` library  
+and set Human `config.backend` to `tensorflow`  
+
+If using `tfjs-node-gpu` module and there is no available GPU acceleratrion, backend will print warning messages  
+during execution and will fall back to CPU execution model instead  
+
+GPU acceleration in NodeJS is currently supported for nVidia GPU cards

+For requirements and how to unable GPU acceleration using `tfjs-node-gpu` in  
+native **Linux**, **Windows** or **Windows WSL2** environments,  
+see appropriate docs on [nVidia CUDA](https://developer.nvidia.com/cuda-toolkit)

+## WebGPU Backend
+
+In the long-term, `WebGPU` backend will superseed existing `WebGL` backend - it's intention is to support same workflows and features while having lower overhead while communicating with GPU  
+
+Currently, WebGPU support is only present in Canary version of [Google Chrome](https://www.google.com/chrome/canary/)  
+And must be explicitly enabled via `--enable-unsafe-gpu` flag  
+
+Due to it's experimental nature `WebGPU` module is not bundled with `Human` and instead it has to be manually loaded  
+After `WebGPU` has been loaded, simply set Human `config.backend` to `WebGPU` and it will perform additional checks and initializations as needed  
+
+Note that `@tensorflow/tfjs-backend-webgpu` is currently in alpha phase of development and released packages are often too old  
+Instead, it is recommended to build `@tensorflow/tfjs-backend-webgpu` from sources directly from `main` branch
