+# MLC-LLM Documentation
+
+The documentation was built upon [Sphinx](https://www.sphinx-doc.org/en/master/).
+
+## Dependencies
+
+Run the following command in this directory to install dependencies first:
+
+```bash
+pip3 install -r requirements.txt
+```
+
+## Build the Documentation
+
+Then you can build the documentation by running:
+
+```bash
+make html
+```
+
+## View the Documentation
+
+Run the following command to start a simple HTTP server:
+
+```bash
+cd _build/html
+python3 -m http.server
+```
+
+Then you can view the documentation in your browser at `http://localhost:8000` (the port can be customized by appending ` -p PORT_NUMBER` in the python command above).

+Adding Models
+=============
+
+WebLLM allows you to compile custom language models using `MLC LLM <https://llm.mlc.ai/>`_ and then serve compiled model through WebLLM.
+
+For instructions of how to compile and add custom models to WebLLM, check the `MLC LLM documentation here <https://llm.mlc.ai/docs/deploy/webllm.html>`_.

+Building From Source
+====================
+
+Clone the Repository
+---------------------
+.. code-block:: bash
+
+   git clone https://github.com/mlc-ai/web-llm.git
+   cd web-llm
+
+Install Dependencies
+---------------------
+.. code-block:: bash
+
+   npm install
+
+Build the Project
+-----------------
+.. code-block:: bash
+
+   npm run build
+
+Test Changes
+------------
+
+To test you changes, you can reuse any existing example or create a new example for your new functionality to test.
+
+Then, to test the effects of your code change in an example, inside ``examples/<example>/package.json``, change from ``"@mlc-ai/web-llm": "^0.2.xx"`` to ``"@mlc-ai/web-llm": ../...`` to let it reference you local code.
+
+.. code-block:: bash
+
+   cd examples/<example>
+   # Modify the package.json

+👋 Welcome to WebLLM
+====================
+
+`GitHub <https://github.com/mlc-ai/web-llm>`_ | `WebLLM Chat <https://chat.webllm.ai/>`_ | `NPM <https://www.npmjs.com/package/@mlc-ai/web-llm>`_ | `Discord <https://discord.gg/9Xpy2HGBuD>`_
+
+WebLLM is a high-performance in-browser language model inference engine that brings large language models (LLMs) to web browsers with hardware acceleration. With WebGPU support, it allows developers to build AI-powered applications directly within the browser environment, removing the need for server-side processing and ensuring privacy.
+
+It provides a specialized runtime for the web backend of MLCEngine, leverages
+`WebGPU <https://www.w3.org/TR/webgpu/>`_ for local acceleration, offers OpenAI-compatible API,
+and provides built-in support for web workers to separate heavy computation from the UI flow.
+
+Key Features
+------------
+- 🌐 In-Browser Inference: Run LLMs directly in the browser
+- 🚀 WebGPU Acceleration: Leverage hardware acceleration for optimal performance
+- 🔄 OpenAI API Compatibility: Seamless integration with standard AI workflows
+- 📦 Multiple Model Support: Works with Llama, Phi, Gemma, Mistral, and more
+
+Start exploring WebLLM by `chatting with WebLLM Chat <https://chat.webllm.ai/>`_, and start building webapps with high-performance local LLM inference with the following guides and tutorials.
