 A small javascript library to develop WebAR apps. It is based on [jsartoolkitNFT](https://github.com/webarkit/jsartoolkitNFT) a lighter version of jsartoolkit5 only with **NFT** markerless technology. It uses [ARnft-threejs](https://github.com/webarkit/ARnft-threejs) for the rendering part.

-## Usage
+## 🏎️ SIMD Feature
+
+The ARnft library now includes support for SIMD (Single Instruction, Multiple Data) to enhance performance by parallelizing data processing tasks. This feature is particularly useful for applications requiring high computational power, such as augmented reality.
+
+To see the SIMD feature in action, you can try the `arNFT_simd_example.html` example:
