+# @loopback/openapi-spec-builder
+
+Make it easy to create OpenAPI (Swagger) specification documents in your
+tests using the builder pattern.
+
+## Overview
+
+Creating a full OpenAPI spec document in automated tests is rather cumbersome,
+long JSON-like objects pollute the test test code and make it difficult
+for readers to distinguish between what's important in the test and what's just
+shared swagger boilerplate.
+
+OpenApiSpecBuilder utilizes
+[Test Data Builder pattern](http://www.natpryce.com/articles/000714.html)
+to provide a TypeScript/JavaScript API allowing users to create
+full OpenAPI Spec documents in few lines of code.
+
+## Installation
+
+```shell
+$ npm install --save-dev @loopback/openapi-spec-builder
+```
+
+_This package is typically used in tests, save it to `devDependencies` via `--save-dev`._
+
+## Basic use
+
+```ts
+import {givenOpenApiSpec, OpenApiSpecBuilder} from '@loopback/openapi-spec-builder';
+
+const spec = givenOpenApiSpec()
+  .withOperationReturningString('get', '/hello', 'greet')
+  .build();
+
+// which is equivalent to the following longer form
+
+const spec = new OpenApiSpecBuilder()
+  .withOperation('get', '/hello', {
+    'x-operation-name': 'greet',
+    responses: {
+      '200': { type: 'string' },
+    },
+  })
+  .build();
+
+// the spec
+
+const spec = {
+  basePath: '/',
+  paths: {
+    '/hello': {
+      get: {
+        'x-operation-name': 'greet',
+        responses: {
+          '200': { type: 'string' },
+        },
+      }
+    }
+  }
+};
+```
