+## Quick Install
+
+```sh
+git clone https://github.com/GradientHQ/parallax.git
+cd parallax
+./install.sh
+source .venv/bin/activate
+```
+
+The install script installs `uv` if needed, creates `.venv`, installs Parallax,
+and builds the `vllm-rs` frontend binary into `.venv/bin`. Use
+`./install.sh --extras gpu` on Linux/WSL GPU hosts or `./install.sh --extras mac`
+on Apple silicon macOS. For development dependencies, use `--extras gpu,dev` or
+`--extras mac,dev`.

 ### From Source
-#### For Linux/WSL (GPU):
-Note: If you are using DGX Spark, please refer to the Docker installation section
+
+The source install script installs `uv` if needed, creates `.venv`, installs
+Parallax, and builds the `vllm-rs` frontend binary into `.venv/bin`.
+
 ```sh
 git clone https://github.com/GradientHQ/parallax.git
 cd parallax
-pip install -e '.[gpu]'
+./install.sh
+source .venv/bin/activate
 ```
 
-#### For macOS (Apple silicon):
-
-We recommend macOS users to create an isolated Python virtual environment before installation.
+The script automatically installs `mac` extras on macOS and `gpu` extras on
+Linux. You can also choose explicitly:
 
 ```sh
-git clone https://github.com/GradientHQ/parallax.git
-cd parallax
+# Linux/WSL GPU
+./install.sh --extras gpu
 
-# Enter Python virtual environment
-python3 -m venv ./venv
-source ./venv/bin/activate
-
-pip install -e '.[mac]'
+# macOS Apple silicon
+./install.sh --extras mac
 ```
 
-Next time to re-activate this virtual environment, run ```source ./venv/bin/activate```.
-
-#### Extra step for development:
+For development dependencies:
 ```sh
-pip install -e '.[dev]'
+./install.sh --extras gpu,dev
+# or
+./install.sh --extras mac,dev
 ```
 
+To use a specific supported Python version, pass `--python`, for example
+`./install.sh --python 3.12`.
+
+Next time to re-activate this virtual environment, run ```source .venv/bin/activate```.
