 ## 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.
+
+## Local Build
+
+As an alternative to downloading via pip, you may build the Python bindings from source.
 
 ### Prerequisites

 ### Building the python bindings
 
-**NOTE**: If you are doing this on a Windows machine, you must build the GPT4All backend using [MinGW64](https://www.mingw-w64.org/) compiler.
+1. Clone GPT4All and change directory:
+```
+git clone --recurse-submodules https://github.com/nomic-ai/gpt4all.git
+cd gpt4all/gpt4all-backend
+```
+
+2. Build the backend.
 
-1. Setup `llmodel`
+If you are using Windows and have Visual Studio installed:
+```
+cmake -B build
+cmake --build build --parallel --config RelWithDebInfo
+```
 
+For all other platforms:
 ```
-git clone --recurse-submodules https://github.com/nomic-ai/gpt4all.git
-cd gpt4all/gpt4all-backend/
-mkdir build
-cd build
-cmake ..
-cmake --build . --parallel  # optionally append: --config Release
+cmake -B build -DCMAKE_BUILD_TYPE=RelWithDebInfo
+cmake --build build --parallel
 ```
-Confirm that `libllmodel.*` exists in `gpt4all-backend/build`.
 
-2. Setup Python package
+`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 .
+pip install -e .
 ```
