 Compared with StarPerf 1.0, StarPerf 2.0 is fully implemented in Python and no longer depends on any third-party orbit analysis or computation tools. You only need to ensure that **Python 3.10** or above is installed on your system.
 
-You can install all required dependencies at once using the following commands:
+# Installation
+
+We recommend using [uv](https://github.com/astral-sh/uv), a fast Python package and project manager, to manage dependencies and virtual environments for this project.
+
+**(1) Install uv:**
+
+MacOS/Linux:
 
 ```bash
-cd StarPerf_Simulator
-pip install -r requirements.txt
+# MacOS/Linux
+curl -LsSf https://astral.sh/uv/install.sh | sh
+# Alternative for MacOS
+brew install uv
 ```
 
-This will automatically install all necessary libraries to ensure the system runs properly. Specifically, we used the following packages to support the simulation: 
-
-- h3==4.0.0b2
-- h5py==3.10.0
-- numpy==1.24.4
-- openpyxl==3.1.2
-- importlib-metadata==6.8.0
-- skyfield==1.46
-- sgp4==2.22
-- pandas==2.1.0
-- poliastro==0.17.0
-- astropy==5.3.3
-- networkx==3.1
-- requests==2.31.0
-- jenkspy==0.4.0
-- pyecharts==2.0.4
-- global_land_mask==1.0.0
-- ephem==4.2

-# StarPerf overview and processing flow
+Windows:
+
+```powershell
+powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
+```
+
+For more installation options, please refer to [official uv documentation](https://docs.astral.sh/uv/getting-started/installation/).
+
+**(2) Installing Dependencies:**
+
+Once you have cloned the repository, you can install all required dependencies using the following `uv` command:
+
+```bash
+cd StarPerf_Simulator/
+uv sync
+```
+
+This will automatically create a virtual environment and install all necessary libraries.
+
+# StarPerf Overview and Processing Flow
 
 You can directly run our simulation example using the following command:
 
 ```bash
-python3 StarPerf.py
+uv run python StarPerf.py
 ```
 
 Of course, you can also write your own simulation scripts. For specific guidelines and important notes, please refer to [interface\_convention](./docs/interface_convention.pdf).
