 # openapi-python-client-action
-GitHub Action to generate a python client package from an openapi spec
+The official GitHub Action for [openapi-python-client](https://github.com/triaxtec/openapi-python-client) - generates a modern Python client package from an OpenAPI document
+
+## Inputs
+
+### `openapi-python-client-version`
+
+The version of the openapi-python-client package to use. If unspecified the latest released version will be used.
+
+### `openapi-file`
+
+The path (with respect to the current directory/the workspace) to the OpenAPI document (both JSON and YAML are supported). Defaults to just "openapi.json" i.e. a file in the current directory called openapi.json.
+
+### `openapi-url`
+
+The url of the OpenAPI document. Overrides `openapi-file` - If unspecified the value of the `openapi-file` input (which defaults to just `openapi.json`) will be used to generate the client.
+
+### `config-file`
+
+The path (with respect to the current directory/the workspace) to the config.yml to be used with openapi-python-client. Configuaration is not required so if this is unspecified then no configuration will be passed along. See [openapi-python-client's README](https://github.com/triaxtec/openapi-python-client#configuration) for available configuration
+
+## Outputs
+
+No outputs are returned.
+The generated client is placed in the current directory. The name of the package (unless configured differently) will be `title-client` where "title" comes from the field with the same name within the `info` section of the openapi document.
+
+## Example usage
+```yaml
+jobs:
+  generate-python-client:
+    runs-on: ubuntu-latest
+    name: Example
+    steps:
+
+      # Checkout your code
+      - name: Checkout
+        uses: actions/checkout@v2
+
+      # Generate your openapi document (if you don't write it manually)
+
+      # Use the action to generate a client package
+      # This uses all defaults (latest version, openapi.json in the current workspace, no configuration)
+      - name: Generate Python Client
+        uses: triaxtec/openapi-python-client-action@v1
+
+      # Do something with the generated client (likely publishing it somewhere)
+      # Here we assume that the info/title in the openapi document was "example-project"
+      - name: Do something with the client
+        run: |
+          cd example-project-client
+```
