 ## Usage
 
-Include the action in your workflow yaml file with the following arguments:
+Include the action in your workflow yaml:
 
 ```yaml
 steps:
-    ...
-    - uses: pdm-project/setup-pdm@v3
-      name: Setup PDM
-      with:
-        python-version: 3.9              # Version range or exact version of a Python version to use, the same as actions/setup-python
-        architecture: x64                # The target architecture (x86, x64) of the Python interpreter. the same as actions/setup-python
-        version: 2.7.4                   # The version of PDM to install. Leave it as empty to use the latest version from PyPI, or 'head' to use the latest version from GitHub
-        prerelease: false                # Allow prerelease versions of PDM to be installed
-        enable-pep582: false             # Enable PEP 582 package loading globally
-        allow-python-prereleases: false  # Allow prerelease versions of Python to be installed. For example if only 3.12-dev is available, 3.12 will fallback to 3.12-dev
-        update-python: true              # Update the environment with the requested python version
+    - uses: actions/checkout@v3
+    - name: Setup PDM
+      uses: pdm-project/setup-pdm@v3
+    # You are now able to use PDM in your workflow
     - name: Install dependencies
-      run: pdm install                   # Then you can use pdm in the following steps.
-    ...
+      run: pdm install
 ```
 
 You don't need `actions/setup-python` actually.
