+# OpenAPI Generator CLI (Angular)
+
+Based on [@openapitools/openapi-generator-cli](https://www.npmjs.com/package/@openapitools/openapi-generator-cli). Unlike the original one, it allows you to publish typescript-angular project.
+
+**Now only for Angular.**
+
+> OpenAPI Generator allows generation of API client libraries (SDK generation), server stubs, documentation and configuration automatically given an OpenAPI Spec (both 2.0 and 3.0 are supported). Please see OpenAPITools/openapi-generator.
+
+## Usage
+
+```shell
+vality-openapi ./web_deploy/swagger.json
+```
