 ### 3. Initialize App
 
 ```typescript
 import express from 'express'
-import { Application } from '@armco/node-starter-kit/v2'
-import { createLoggerPlugin, createDatabasePlugin } from '@armco/node-starter-kit/v2'
-import { initHelmet, initCors, initJwt } from '@armco/node-starter-kit/v2'
+import { Application } from '@armco/node-starter-kit'
 
 async function main() {
   const app = express()
-  
+
+  // You can register routes before build(); NSK will ensure configured middlewares
+  // run before existing routes.
+  app.get('/', (_req, res) => res.json({ ok: true }))
+
   const nsk = await Application.create(app)
-    .plugin(createLoggerPlugin())
-    .plugin(createDatabasePlugin({ uri: process.env.MONGO_URI }))
-    .build()
-  
+    .build() // loads armcorc.json + starts plugins + injects configured middlewares
+
   const logger = nsk.getContainer().resolve('logger')
-  
-  initHelmet(app, {}, logger)
-  initCors(app, { allowedOrigins: ['http://localhost:3000'] }, logger)
-  
-  app.get('/', (req, res) => {
-    logger.info('Request received')
-    res.json({ message: 'Hello World' })
-  })
-  
+  logger.info('NSK initialized')
+
   app.listen(3000, () => logger.info('Server started on :3000'))
 }
 
 main().catch(console.error)
 ```
 
+**Notes**
+- **Config is the source of truth**: middlewares are injected only if configured in `armcorc.json`.
+- **`arOptions` vs `libOptions`**: `arOptions` controls Armco behavior (like whitelists / url patterns), `libOptions` are passed to third-party libs.
+- **Lazy-loaded middleware libs**: third-party middleware libraries are loaded only when that middleware is configured.
