How to create a new project

# create main.tf
cat << 'EOF' > main.tf
terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 4.16"
    }
  }

  required_version = ">= 1.2.0"
}

# AWS config
# leave empty to read the settings from the AWS CLI configuration
provider "aws" {}
EOF

# this will download provider plugin into .terraform subdir
terraform init
