 # 🚀 Terraform Kubernetes — Starter Kit for Docker Desktop
 
+This starter kit is designed for local Kubernetes experimentation using Terraform. It provides a preconfigured setup with certificate management, ingress routing, and load balancing, making it easy to test, learn, and prototype cloud-native deployments.

+## 👨‍💻 Who is it for?
+- DevOps Engineers & SREs who want a sandbox for testing infrastructure automation.
+- Developers exploring Kubernetes deployments without cloud costs.
+- Teams learning Terraform and Kubernetes best practices in a safe, local environment.

 ## 📂 Project Structure
-This Terraform project is designed to deploy and manage a Kubernetes cluster with essential services such as MetalLB, Cert-Manager, Ingress-Nginx, and Echo Server. The structure follows best practices for modularity and maintainability.

 ### **Requirements**
 For local usage, for example, in Docker Desktop you might want to use selfsigned certificates. To do that process easy just install the tool `mkcert`.
 ```sh
+# https://github.com/FiloSottile/mkcert?tab=readme-ov-file#installation
 brew install mkcert
 mkcert -install
 ```
 
 ## 🛠️ Setup and Deployment

+The best way is fork the repo. But it's up to you.

 1. **Set selfsigned CA certificate and key**
    For local usage you have set some TF_VAR
