 ## GPT4All: An ecosystem of open-source on-edge large language models.

+GPT4All is an ecosystem to run **powerful** and **customized** large language models that work locally on consumer grade CPUs and any GPU. Note that your CPU needs to support [AVX or AVX2 instructions](https://en.wikipedia.org/wiki/Advanced_Vector_Extensions).
 
 Learn more in the [documentation](https://docs.gpt4all.io).
 
-The goal is simple - be the best instruction tuned assistant-style language model that any person or enterprise can freely use, distribute and build on.
+A GPT4All model is a 3GB - 8GB file that you can download and plug into the GPT4All open-source ecosystem software. **Nomic AI** supports and maintains this software ecosystem to enforce quality and security alongside spearheading the effort to allow any person or enterprise to easily train and deploy their own on-edge large language models.

+On Windows and Linux, building GPT4All requires the complete Vulkan SDK. You may download it from here: https://vulkan.lunarg.com/sdk/home

 ## Installation
 
+The easiest way to install the Python bindings for GPT4All is to use pip:
+
 ```
 pip install gpt4all
 ```
 
-## Local Build Instructions
+This will download the latest version of the `gpt4all` package from PyPI.
 
-**NOTE**: If you are doing this on a Windows machine, you must build the GPT4All backend using [MinGW64](https://www.mingw-w64.org/) compiler.
+## Local Build
 
-1. Setup `llmodel`
+As an alternative to downloading via pip, you may build the Python bindings from source.
 
+### Prerequisites
+
+On Windows and Linux, building GPT4All requires the complete Vulkan SDK. You may download it from here: https://vulkan.lunarg.com/sdk/home
+
+macOS users do not need Vulkan, as GPT4All will use Metal instead.
+
+### Building the python bindings
+
+1. Clone GPT4All and change directory:
 ```
-git clone --recurse-submodules git@github.com:nomic-ai/gpt4all.git
-cd gpt4all/gpt4all-backend/
-mkdir build
-cd build
-cmake ..
-cmake --build . --parallel  # optionally append: --config Release
+git clone --recurse-submodules https://github.com/nomic-ai/gpt4all.git
+cd gpt4all/gpt4all-backend
 ```
-Confirm that `libllmodel.*` exists in `gpt4all-backend/build`.
 
-2. Setup Python package
+2. Build the backend.
 
+If you are using Windows and have Visual Studio installed:
+```
+cmake -B build
+cmake --build build --parallel --config RelWithDebInfo
+```
+
+For all other platforms:
+```
+cmake -B build -DCMAKE_BUILD_TYPE=RelWithDebInfo
+cmake --build build --parallel
+```
+
+`RelWithDebInfo` is a good default, but you can also use `Release` or `Debug` depending on the situation.
+
+2. Install the Python package:
 ```
 cd ../../gpt4all-bindings/python
-pip3 install -e .

 #### Troubleshooting and FAQ
 *My LocalDocs plugin isn't using my documents*
 
 - Make sure LocalDocs is enabled for your chat session (the DB icon on the top-right should have a border)
-- Try to modify your prompt to be more specific and use terminology that is in your document. This will increase the likelihood that LocalDocs matches document snippets for your question.
 - If your document collection is large, wait 1-2 minutes for it to finish indexing.
 
 
 #### LocalDocs Roadmap
-- Embedding based semantic search for retrieval. 
 - Customize model fine-tuned with retrieval in the loop.
 - Plugin compatibility with chat client server mode.
