Hello, I am a PR summary agent on flows.network. Here are my reviews of code commits in this PR.

---

This change is not necessary as the dynamic library file name should be libwasmedgePluginWasiNN.so on Linux and libwasmedgePluginWasiNN.dylib on MacOS, regardless of the backend used.
2. Explains that MLX (Machine Learning eXtended Library) is a part of WebAssembly specification but it's not defined yet. However, it should be clarified that MLX is an open source library for running machine learning models inside WebAssembly.
3. Instructions to build WasmEdge with MLX as the backend are provided in the pull request. Developers need to follow these steps and compile WasmEdge with WASMEDGE_PLUGINS=wasmedgePlugin, MLX_PATH=<path-to-mlx> in order to link it dynamically at runtime.
4. It's important that users have the MLX library installed correctly for WASI-NN to work properly. The path of the MLX library (MLX_PATH) should match with where the MLX library is actually located on their system.

The Pull Request titled "[Docs] Add MLX backend" is proposing to update the documentation of the WasmEdge project by adding instructions on how to build and install this project with the MLX backend for WASI-NN, a neural network API that provides support to execute machine learning models in WebAssembly. This change will allow users to use the MLX (a Machine Learning eXtended Library) as the backend for running machine learning operations inside WebAssembly.
