+## Use uv to install a custom Python version
+
+If you want to use a different Python version than your Linux distribution provides, you can use [uv](https://github.com/astral-sh/uv) to set it up. Note that this will only work for the Gunicorn setup. First install `uv`:
+
+```bash
+curl -LsSf https://astral.sh/uv/install.sh | sh
+```

+Then you can create a virtual environment with the desired Python version using, e.g.:
+
+```bash
+uv venv env --seed --python 3.12
+```

If you decide otherwise, it is relatively easy to install a different Python version using [uv](https://github.com/astral-sh/uv). Instructions can be found [here](../advanced/index).
