+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+
+## Requirements.
+
+Python 3.7+
+
+## Installation & Usage
+### pip install
+
+If the python package is hosted on a repository, you can install directly using:
+
+```sh
+pip install git+https://github.com/GIT_USER_ID/GIT_REPO_ID.git
+```
+(you may need to run `pip` with root permission: `sudo pip install git+https://github.com/GIT_USER_ID/GIT_REPO_ID.git`)
+
+Then import the package:
+```python
+import openapi_client
+```
+
+### Setuptools
+
+Install via [Setuptools](http://pypi.python.org/pypi/setuptools).
+
+```sh
+python setup.py install --user
+```
+(or `sudo python setup.py install` to install the package for all users)
+
+Then import the package:
+```python
+import openapi_client
+```
+
+## Getting Started
+
+Please follow the [installation procedure](#installation--usage) and then run the following:
+
+```python
+from __future__ import print_function

+# Defining the host is optional and defaults to http://localhost:3000
+# See configuration.py for a list of all supported configuration parameters.
+configuration = openapi_client.Configuration(
+    host = "http://localhost:3000"
+)
+
+
+
+# Enter a context with an instance of the API client
+with openapi_client.ApiClient(configuration) as api_client:
+    # Create an instance of the API class
+    api_instance = openapi_client.BodyApi(api_client)
+    pet = openapi_client.Pet() # Pet | Pet object that needs to be added to the store (optional)
