+
+# You can match any string of characters against a directory, file or extension with a single 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:

+# OpenAPI Petstore - MicroProfile Rest Client & MicroProfile Server
+
+This is a sample server Petstore server. For this sample, you can use the api key `special-key` to test the authorization filters.
+
+## Overview
+This API client was generated by the [OpenAPI Generator](https://openapi-generator.tech) project.
+[MicroProfile Rest Client](https://github.com/eclipse/microprofile-rest-client) is a type-safe way of calling
+REST services. The generated client contains an interface which acts as the client, you can inject it into dependent classes.
