 ## Quick Start
 
-To get started quickly, navigate to the [`live/core`](./live/core) directory and follow the instructions in the [README](./live/core/README.md). This directory contains the Terraform root module for our core infrastructure, including Terraform variables and backend configuration. Additionally, we provide post-deployment steps in the [README](./live/core/README.md#post-deployment-steps) to help you test the setup and get familiar with the infrastructure.
+Check the [Live Infrastructure](#live-infrastructure) section for more information about existing infrastructure modules and how to use them.
+
+Once you have chosen the infrastructure module you want to use, move to the module directory and follow the instructions in the README file.
 
 ## Live Infrastructure
 
 The `live` directory houses our live infrastructure. This is where you'll find our Terraform variables, backend configuration, and Terraform root modules.

+It is recommended to create a separate directory for each environment (e.g., `dev`, `staging`, `prod`) and region (e.g., `us-east-1`, `us-west-2`, `eu-west-1`). This allows you to easily manage and deploy your infrastructure.
