-## Using the pip-install input
-
-The `pip-install` input allows you to install dependencies as part of the Python setup step.

-```yaml
-      steps:
-      - uses: actions/checkout@v6
-      - name: Set up Python
-        uses: actions/setup-python@v6
-        with:
-          python-version: '3.13'
-          pip-install: -r requirements.txt
-```
-> Note: This feature is intended for standard pip-based dependency installations.
-For complex workflows, or alternative package managers (e.g., poetry, pipenv), we recommend using separate steps to maintain clarity and flexibility.
-
-> The `pip-install` input mirrors the flexibility of a standard pip install command and supports most of its arguments.
