How to use this repo?

[Tobjoern]

In your talk you mentioned this repository,
I read through all the README.md files in configure_demo, but I still can't figure out, how to run this.

I tried running the script in configure_demo with 'terraform init',
but I received the following error:

Initializing Terraform Cloud...
╷
│ Error: Failed to read organization "ned-in-the-cloud" at host app.terraform.io
│ 
│   on terraform.tf line 15, in terraform:
│   15:     organization = "ned-in-the-cloud"
│ 
│ Encountered an unexpected error while reading the organization settings: organization "ned-in-the-cloud" at host app.terraform.io not found.
│ 
│ Please ensure that the organization and hostname are correct and that your API token for app.terraform.io is valid.

Do I need to create a workspace or so in terraform?
