+# Native uv Python and package management
+
+This tutorial is an alternative to *Option 1: Using uv* in the [README.md](./README.md) document for those who prefer `uv`'s native commands over the `uv pip` interface. While `uv pip` is faster than pure `pip`, `uv`'s native interface is even faster than `uv pip` as it has less overhead and doesn't have to handle legacy support for PyPy package dependency management.
+
+Otherwise, similar to *Option 1: Using uv* in the [README.md](./README.md) , this section guides you through the Python setup and package installation procedure using `uv`. 
+
+In this tutorial, I am using a computer running macOS, but this workflow is similar for Linux machines and may work for other operating systems as well.
+
+
+ 
+## 1. Install uv
+
+Uv can be installed as follows, depending on your operating system.
+
+ 
+**macOS and Linux**
+
+```bash
+curl -LsSf https://astral.sh/uv/install.sh | sh
+```
+
+or
+
+```bash
+wget -qO- https://astral.sh/uv/install.sh | sh
+```
+
+ 
+**Windows**
+
+```bash
+powershell -c "irm https://astral.sh/uv/install.ps1 | more"
+```
+
+ 
+
+> [!NOTE]
+> For more installation options, please refer to the official [uv documentation](https://docs.astral.sh/uv/getting-started/installation/#standalone-installer).
+
+ 
+## 2. Install Python
+
+You can install Python using uv:
+
+```bash
+uv python install 3.10
+```
+
+ 
+> [!NOTE]  
+> I recommend installing a Python version that is at least 2 versions older than the most recent release to ensure PyTorch compatibility. For example, if the most recent version is Python 3.13, I recommend installing version 3.10 or 3.11. You can find out the most recent Python version by visiting [python.org](https://www.python.org/downloads/).
+
+ 
+## 3. Install Python packages and dependencies
+
+To install all required packages from a `pyproject.toml` file (such as the one located at the top level of this GitHub repository), run the following command, assuming the file is in the same directory as your terminal session:
+
+```bash
+uv add . --dev
+```
+
+<img src="https://sebastianraschka.com/images/LLMs-from-scratch-images/setup/uv-setup/uv-add.png?1" width="700" height="auto" alt="Uv install">
+
+Note that the `uv add` command above will create a separate virtual environment via the `.venv` subfolder.
+
+You can install new packages, that are not specified in the `pyproject.toml` via `uv add`, for example:
+
+```bash
+uv add packaging
+```
+
+&nbsp;
+## Optional: Manage virtual environments manually
+
+Alternatively, you can still install the dependencies directly from the repository using `uv pip install`. Note that this requires creating and activating the virtual environment manually:
+
+&nbsp;
+**1. Create a new virtual environment**
+
+Run the following command to manually create a new virtual environment, which will be saved via a new `.venv` subfolder:
+
+```bash
+uv venv --python=python3.10
+```
+
+&nbsp;
+**2. Activate virtual environment**
+
+Next, we need to activate this new virtual environment.
+
+On macOS/Linux:
+
+```bash
+source .venv/bin/activate
+```
+
+On Windows (PowerShell):
+
+```bash
+.venv\Scripts\activate
+```
+
+&nbsp;
+**3. Install dependencies**
+
+Finally, we can install dependencies from a remote location using the `uv pip` interface:
+
+```bash
+uv pip install -U -r https://raw.githubusercontent.com/rasbt/LLMs-from-scratch/refs/heads/main/requirements.txt
+```
+
+
+
+&nbsp;
+## 4. Run Python code
+
+&nbsp;
+**Finalizing the setup**
+
+Your environment should now be ready to run the code in the repository.
+
+Optionally, you can run an environment check by executing the `python_environment_check.py` script in this repository: 
+
+```bash
+uv run python setup/02_installing-python-libraries/python_environment_check.py
+```
+
+
+
+<img src="https://sebastianraschka.com/images/LLMs-from-scratch-images/setup/uv-setup/uv-run-check.png?1" width="700" height="auto" alt="Uv install">
+
+
+
+Or, if you don't want to type `uv run python` ever time you execute code, manually activate the virtual environment first. 
+
+On macOS/Linux:
+
+```bash
+source .venv/bin/activate
+```
+
+On Windows (PowerShell):
+
+```bash
+.venv\Scripts\activate
+```
+
+Then, run:
+
+
+```bash
+python setup/02_installing-python-libraries/python_environment_check.py
+```
+
+&nbsp;
+**Launching JupyterLab**
+
+You can launch a JupyterLab instance via:
+
+```bash
+uv run jupyter lab
+```
+
+Or, if you manually activated the environment as described earlier, you can drop the `uv run` prefix.
