+
+{{#unescapedAppDescription}}

+
+Generated by OpenAPI Generator {{generatorVersion}}{{^hideGenerationTimestamp}} ({{generatedDate}}){{/hideGenerationTimestamp}}.
+
+## Requires
+
+* Kotlin 2.0.20
+* Gradle 8.10.2
+
+## Build
+
+First, create the gradle wrapper script:
+
+```
+gradle wrapper
+```
+
+Then, run:
+
+```
+./gradlew check assemble
+```
+
+This runs all tests and packages the library.
+
+## Running
+
+The server builds as a fat jar with a main entrypoint. To start the service, run `java -jar ./build/libs/{{artifactId}}.jar`.
+
+You may also run in docker:
+
+```
+docker build -t {{artifactId}} .
+docker run -p 8080:8080 {{artifactId}}
+```
+
+## Features/Implementation Notes
+
+* Supports JSON inputs/outputs, File inputs, and Form inputs (see ktor documentation for more info).
+* ~Supports collection formats for query parameters: csv, tsv, ssv, pipes.~
+* Some Kotlin and Java types are fully qualified to avoid conflicts with types defined in OpenAPI definitions.

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# 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

+# org.openapitools.server - Kotlin Server library for OpenAPI Petstore
+
+This is a sample server Petstore server. For this sample, you can use the api key `special-key` to test the authorization filters.
+
+Generated by OpenAPI Generator 7.11.0-SNAPSHOT.
+
+## Requires
+
+* Kotlin 2.0.20
+* Gradle 8.10.2
+
+## Build
+
+First, create the gradle wrapper script:
+
+```
+gradle wrapper
+```
+
+Then, run:
+
+```
+./gradlew check assemble
+```
+
+This runs all tests and packages the library.
+
+## Running
+
+The server builds as a fat jar with a main entrypoint. To start the service, run `java -jar ./build/libs/kotlin-server.jar`.
+
+You may also run in docker:
+
+```
+docker build -t kotlin-server .
+docker run -p 8080:8080 kotlin-server
+```
+
+## Features/Implementation Notes
+
+* Supports JSON inputs/outputs, File inputs, and Form inputs (see ktor documentation for more info).
+* ~Supports collection formats for query parameters: csv, tsv, ssv, pipes.~
+* Some Kotlin and Java types are fully qualified to avoid conflicts with types defined in OpenAPI definitions.
+
+
+## Documentation for API Endpoints
+
+All URIs are relative to *http://petstore.swagger.io/v2*
