+### Using custom templates
+
+This feature leverages Jinja2's [ChoiceLoader](https://jinja.palletsprojects.com/en/2.11.x/api/#jinja2.ChoiceLoader) and [FileSystemLoader](https://jinja.palletsprojects.com/en/2.11.x/api/#jinja2.FileSystemLoader). This means you do _not_ need to customize every template. Simply copy the template(s) you want to customize from [the default template directory](openapi_python_client/templates) to your own custom template directory (file names _must_ match exactly) and pass the template directory through the `custom_template_path` flag to the `generate` and `update` commands. For instance, 
+
+```
+openapi-python-client update \
+  --url https://my.api.com/openapi.json \
+  --custom-template-path=relative/path/to/mytemplates
+```
+
+_Be forewarned, this is a beta-level feature in the sense that the API exposed in the templates is undocumented and unstable._
+
 ## What You Get
 
 1. A `pyproject.toml` file with some basic metadata intended to be used with [Poetry].

+# my-test-api-client
+A client library for accessing My Test API
+
+## Usage
+First, create a client:
+
+```python
+from my_test_api_client import Client
+
+client = Client(base_url="https://api.example.com")
+```
+
+If the endpoints you're going to hit require authentication, use `AuthenticatedClient` instead:
+
+```python
+from my_test_api_client import AuthenticatedClient
+
+client = AuthenticatedClient(base_url="https://api.example.com", token="SuperSecretToken")
+```
+
+Now call your endpoint and use your models:
+
+```python
+from my_test_api_client.models import MyDataModel
+from my_test_api_client.api.my_tag import get_my_data_model
+
+my_data: MyDataModel = get_my_data_model(client=client)
+```
+
+Or do the same thing with an async version:
+
+```python
+from my_test_api_client.models import MyDataModel
+from my_test_api_client.async_api.my_tag import get_my_data_model
+
+my_data: MyDataModel = await get_my_data_model(client=client)
+```
+
+Things to know:
+1. Every path/method combo becomes a Python function with type annotations. 
+1. All path/query params, and bodies become method arguments.
+1. If your endpoint had any tags on it, the first tag will be used as a module name for the function (my_tag above)
+1. Any endpoint which did not have a tag will be in `my_test_api_client.api.default`
+1. If the API returns a response code that was not declared in the OpenAPI document, a 
+    `my_test_api_client.api.errors.ApiResponseError` wil be raised 
+    with the `response` attribute set to the `httpx.Response` that was received.
+
+
+## Building / publishing this Client
+This project uses [Poetry](https://python-poetry.org/) to manage dependencies  and packaging.  Here are the basics:
+1. Update the metadata in pyproject.toml (e.g. authors, version)
+1. If you're using a private repository, configure it with Poetry
+    1. `poetry config repositories.<your-repository-name> <url-to-your-repository>`
+    1. `poetry config http-basic.<your-repository-name> <username> <password>`
+1. Publish the client with `poetry publish --build -r <your-repository-name>` or, if for public PyPI, just `poetry publish --build`
+
+If you want to install this client into another project without publishing it (e.g. for development) then:
+1. If that project **is using Poetry**, you can simply do `poetry add <path-to-this-client>` from that project
+1. If that project is not using Poetry:
+    1. Build a wheel with `poetry build -f wheel`
+    1. Install that wheel from the other project `pip install <path-to-wheel>`
