-Installs Python and some extra dependencies
+# Setup Python with dependencies Action
+
+This action installs Python, upgrades `pip` and optionally installs some extra
+dependencies.
+
+Here is an example demonstrating how to use it in a workflow:
+
+```yaml
+jobs:
+  test:
+    name: Test
+    runs-on: ubuntu-20.04
+
+    steps:
+      - name: Checkout code
+        uses: actions/checkout@v4
+      - name: Setup Python
+        uses: frequenz-floss/gh-action-setup-python-with-deps@v0.x.x
+        with:
+          python-version: "3.11"
+          dependencies: "mkdocs"
+      - name: Run mkdocs
+        run: mkdocs --help
+```
+
+## Inputs
+
+* `python-version`: The Python version to use. Required.
+
+   This is passed to the
+   [`actions/setup-python`](https://github.com/actions/setup-python) action.
+
+* `dependencies`: The dependencies to install. Default: "".
+
+  This is passed to the `pip install` command as is, without any shell
+  escaping. If empty, no dependencies are installed.
