 ## Motivation
 Many Docker images including the Terraform and Azure CLI already exist out there, both on the Docker Hub and Github.
 But they all are quite oversized.
 
-The goal is to create a **functional**, **minimalist** and **lightweight** image with these tools in order to reduce network and storage impact.

 You can build the image locally directly from the Dockerfiles.
 
 ```bash
-# Build the Debian based image:
-docker image build -f debian.Dockerfile -t zenika/terraform-azure-cli:debian .
-
 # Build the Alpine based image:
 docker image build -f alpine.Dockerfile -t zenika/terraform-azure-cli:alpine .

+# Build the Debian based image:
+docker image build -f debian.Dockerfile -t zenika/terraform-azure-cli:debian .
 ```
 
 Optionally, it is possible to choose the tools desired versions using [Docker builds arguments](https://docs.docker.com/engine/reference/commandline/build/#set-build-time-variables---build-arg) :
