 ## Quick Start
 
-### 1. Setup Host Environment
+**Note:** For quick startup and verification, only the CPU-based image
+(simulation planning module) is provided. The full GPU-dependent tutorial will
+be released later. We recommend starting with the CPU image because the GPU
+image is large and has complex dependencies, which may not be suitable for
+beginners.
 
-Run the following scripts in order to prepare your host machine, which will
-perform the following steps sequentially:
+### 1. Install Deployment Tool
 
-1. Install Docker (checks if already installed, then proceeds)
-2. Install NVIDIA Container Toolkit (checks if already installed, depends on
-   Docker)
-3. Perform host system configurations
+```bash
+pip install whl-deploy
+```
+
+### 2. Setup Host Environment
+
+Run the following scripts to prepare your host machine. These steps will:
+
+1. Install Docker (checks if already installed)
+2. [skip] Install NVIDIA Container Toolkit (checks if already installed, depends
+   on Docker)
+3. [skip] Perform host system configurations
 
 ```bash
-# setup host
-bash docker/setup_host/setup_host.sh
+whl-deploy setup docker
 ```
