 ### Via CDK
 
-See `NextStandaloneStack` construct in `lib/construct.ts`.
+See `NextStandaloneStack` construct in `cdk/example.ts`.
 
-You can easily create `cdk/app.ts` and use following code:
-```
-#!/usr/bin/env node
-import 'source-map-support/register'
-import * as cdk from 'aws-cdk-lib'
-import * as path from 'path'
-
-import { NextStandaloneStack } from '@sladg/nextjs-lambda'
-
-const assetsZipPath = path.resolve(__dirname, '../next.out/assetsLayer.zip')
-const codeZipPath = path.resolve(__dirname, '../next.out/code.zip')
-const dependenciesZipPath = path.resolve(__dirname, '../next.out/dependenciesLayer.zip')
-
-const app = new cdk.App()
 
-new NextStandaloneStack(app, 'StandaloneNextjsStack-2', {
-	assetsZipPath,
-	codeZipPath,
-	dependenciesZipPath,
-})
-```
+#### Benchmark
 
-This imports pre-made construct, you only need to worry about paths to outputed zip files from CLI `pack` command.
