        Congrats! You have successfully created a terraspace project.
        Check out the created files. Adjust to the examples and then deploy with:

            cd #{name}
            terraspace up demo -y   # to deploy
            terraspace down demo -y # to destroy

        Congrats! You have successfully created a terraspace project.
        Check out the created files.

            cd #{name}

        You can create starter modules and stacks with their generators:

            terraspace new module example
            terraspace new stack demo

        Add your code to them, and deploy when you are ready:

            terraspace up demo -y   # to deploy

        Destroy with:

            terraspace down demo -y # to destroy
