+# 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

+# Go API client for petstore
+
+This spec is mainly for testing Petstore server and contains fake endpoints, models. Please do not use this for any other purpose. Special characters: \" \\
+
+## Overview
+This API client was generated by the [OpenAPI Generator](https://openapi-generator.tech) project.  By using the [OpenAPI-spec](https://www.openapis.org/) from a remote server, you can easily generate an API client.
+
+- API version: 1.0.0
+- Package version: 1.0.0
+- Build package: org.openapitools.codegen.languages.GoClientCodegen
+
+## Installation
+
+Install the following dependencies:
+```
+go get github.com/stretchr/testify/assert
+go get golang.org/x/oauth2
+go get golang.org/x/net/context
+go get github.com/antihax/optional
+```
+
+Put the package under your project folder and add the following in import:
+```golang
+import "./petstore"
+```

+## Documentation For Authorization
+
+## api_key
+- **Type**: API key 
+
+Example
+```golang
+auth := context.WithValue(context.Background(), sw.ContextAPIKey, sw.APIKey{
+	Key: "APIKEY",
+	Prefix: "Bearer", // Omit if not necessary.
+})
+r, err := client.Service.Operation(auth, args)
+```
+## api_key_query
+- **Type**: API key 
+
+Example
+```golang
+auth := context.WithValue(context.Background(), sw.ContextAPIKey, sw.APIKey{
+	Key: "APIKEY",
+	Prefix: "Bearer", // Omit if not necessary.
+})
+r, err := client.Service.Operation(auth, args)
+```
+## http_basic_test
+- **Type**: HTTP basic authentication
+
+Example
+```golang
+auth := context.WithValue(context.Background(), sw.ContextBasicAuth, sw.BasicAuth{
+	UserName: "username",
+	Password: "password",
+})
+r, err := client.Service.Operation(auth, args)
+```
+## petstore_auth
+- **Type**: OAuth
+- **Flow**: implicit
+- **Authorization URL**: http://petstore.swagger.io/api/oauth/dialog
+- **Scopes**: 
+ - **write:pets**: modify pets in your account
+ - **read:pets**: read your pets
+
+Example
+```golang
+auth := context.WithValue(context.Background(), sw.ContextAccessToken, "ACCESSTOKENSTRING")
+r, err := client.Service.Operation(auth, args)
+```
+
+Or via OAuth2 module to automatically refresh tokens and perform user authentication.
+```golang
+import "golang.org/x/oauth2"
+
+/* Perform OAuth2 round trip request and obtain a token */
+
+tokenSource := oauth2cfg.TokenSource(createContext(httpClient), &token)
+auth := context.WithValue(oauth2.NoContext, sw.ContextOAuth2, tokenSource)
+r, err := client.Service.Operation(auth, args)
+```
