## Overview

This repository is a small NestJS API scaffold. Its principal workflow is an HTTP GET request handled by the root controller, which delegates to a service returning a fixed greeting. The bootstrap also configures Swagger documentation and starts the server; the module registers the controller, service, and global configuration. The sampled source establishes these runtime relationships, but the README provides no additional product capabilities.

Main entry points: [`apps/api/src/app.module.ts`](https://github.com/it-mobile-team/entlang/blob/develop/apps/api/src/app.module.ts) (App module), [`apps/api/src/app.controller.ts`](https://github.com/it-mobile-team/entlang/blob/develop/apps/api/src/app.controller.ts) (Root controller), [`apps/api/src/main.ts`](https://github.com/it-mobile-team/entlang/blob/develop/apps/api/src/main.ts) (Server bootstrap), [`apps/api/src/app.service.ts`](https://github.com/it-mobile-team/entlang/blob/develop/apps/api/src/app.service.ts) (Greeting service)
