+Before Getting started, you have to ensure
+
+* [Golang](https://golang.org/dl/) development environment
+* [AWS TypeScript CDK](https://docs.aws.amazon.com/cdk/latest/guide/getting_started.html)
+* Access to AWS Account

 ## Getting started
 
 **Let's have a look on the repository structure**
 
 The structure resembles the standard package layout proposed in [this blog post](https://medium.com/@benbjohnson/standard-package-layout-7cdbc8391fc1):
 
-1. the root package contains core types to describe domain of your application. It contains simple types that has no dependency to technology.
+1. the root package contains core types to describe domain of your application. It contains simple types that has no dependency to technology but their implements core logic and use-cases.
 
 2. Use sub-packages to isolate dependencies to external technologies so that they act as bridge between your domain and technology adaptation.
