+### Install a version defined in a requirements or config file
+
+You can use the `version-file` input to specify a file that contains the version of uv to install.
+This can either be a `pyproject.toml` or `uv.toml` file which defines a `required-version` or
+uv defined as a dependency in `pyproject.toml` or `requirements.txt`.
+
+```yaml
+- name: Install uv based on the version defined in pyproject.toml
+  uses: astral-sh/setup-uv@v6
+  with:
+    version-file: "pyproject.toml"
+```
+
 ### Python version
 
 You can use the input `python-version` to set the environment variable `UV_PYTHON` for the rest of your workflow
