+    Provides online TypeScript editor and Swagger-UI at the same time.
+
+    In the TypeScript editor, client SDK (Software Development Kit) interacting with the remote HTTP server is embedded, 
+    and the SDK also provides the mockup simulator of the HTTP server without actual connection. Of course, if you hope, 
+    you can directly build the SDK library by the CLI command.
+     
+    Furthermore, <b>@nestia/editor</b> supports NestJS server code generation from the OpenAPI (Swagger) document file, 
+    so you can do everything with the OpenAPI document file.

+    It does not require any extra schema definition, but just fine with the pure TypeScript type. 
+    <b>@nestia/sdk</b> analyzes your TypeScript code in the compilation level, and generates OpenAPI
+    document by parsing the programming AST (Abstract Syntax Tree) nodes. 
+    
+    Also, <b>@nestia/sdk</b> supports client side SDK (Software Development Kit) generation, 
+    and it embeds the mockup simulator of the NestJS server without connection.
