-⚠️ This is work in progress. The UX needs to be improved,
-and the docs could be better.
-
-This directory contains a Terraform configuration to deploy
-a bunch of Kubernetes clusters on various cloud providers,
-using their respective managed Kubernetes products.
-
-## With shell wrapper
-
-This is the recommended use. It makes it easy to start N clusters
-on any provider. It will create a directory with a name like
-`tag-YYYY-MM-DD-HH-MM-SS-SEED-PROVIDER`, copy the Terraform configuration
-to that directory, then create the clusters using that configuration.
-
-1. One-time setup: configure provider authentication for the provider(s) that you wish to use.
-
-- Digital Ocean:
-  ```bash
-  doctl auth init
-  ```
-
-- Google Cloud Platform: you will need to create a project named `prepare-tf`
-  and enable the relevant APIs for this project (sorry, if you're new to GCP,
-  this sounds vague; but if you're familiar with it you know what to do; if you
-  want to change the project name you can edit the Terraform configuration)
-
-- Linode:
-  ```bash
-  linode-cli configure
-  ```
-
-- Oracle Cloud: FIXME
-  (set up `oci` through the `oci-cli` Python package)
-
-- Scaleway: run `scw init`
-
-2. Optional: set number of clusters, cluster size, and region.
-
-By default, 1 cluster will be configured, with 2 nodes, and auto-scaling up to 5 nodes.
-
-If you want, you can override these parameters, with the following variables.
-
-```bash
-export TF_VAR_how_many_clusters=5
-export TF_VAR_min_nodes_per_pool=2
-export TF_VAR_max_nodes_per_pool=4
-export TF_VAR_location=xxx
-```
-
-The `location` variable is optional. Each provider should have a default value.
-The value of the `location` variable is provider-specific. Examples:
-
-| Provider      | Example value     | How to see possible values
-|---------------|-------------------|---------------------------
-| Digital Ocean | `ams3`            | `doctl compute region list`
-| Google Cloud  | `europe-north1-a` | `gcloud  compute zones list`
-| Linode        | `eu-central`      | `linode-cli regions list`
-| Oracle Cloud  | `eu-stockholm-1`  | `oci iam region list`
-
-You can also specify multiple locations, and then they will be
-used in round-robin fashion.
-
-For example, with Google Cloud, since the default quotas are very
-low (my account is limited to 8 public IP addresses per zone, and
-my requests to increase that quota were denied) you can do the
-following:
-
-```bash
-export TF_VAR_location=$(gcloud compute zones list --format=json | jq -r .[].name | grep ^europe)
-```
-
-Then when you apply, clusters will be created across all available
-zones in Europe. (When I write this, there are 20+ zones in Europe,
-so even with my quota, I can create 40 clusters.)
-
-3. Run!
-
-```bash
-./run.sh <providername>
-```
-
-(If you don't specify a provider name, it will list available providers.)
-
-4. Shutting down
-
-Go to the directory that was created by the previous step (`tag-YYYY-MM...`)
-and run `terraform destroy`.
-
-You can also run `./clean.sh` which will destroy ALL clusters deployed by the previous run script.
-
-## Without shell wrapper
-
-Expert mode.
-
-Useful to run steps sperarately, and/or when working on the Terraform configurations.
-
-1. Select the provider you wish to use.
-
-Go to the `source` directory and edit `main.tf`.
-
-Change the `source` attribute of the `module "clusters"` section.
-
-Check the content of the `modules` directory to see available choices.
-
-2. Initialize the provider.
-
-```bash
-terraform init
-```
-
-3. Configure provider authentication.
-
-See steps above, and add the following extra steps:
-
-- Digital Coean:
-  ```bash
-  export DIGITALOCEAN_ACCESS_TOKEN=$(grep ^access-token ~/.config/doctl/config.yaml | cut -d: -f2 | tr -d " ")
-  ```
-
-- Linode:
-  ```bash
-  export LINODE_TOKEN=$(grep ^token ~/.config/linode-cli | cut -d= -f2 | tr -d " ")
-  ```
-
-4. Decide how many clusters and how many nodes per clusters you want.
-
-5. Provision clusters.
-
-```bash
-terraform apply
-```
-
-6. Perform second stage provisioning.
-
-This will install an SSH server on the clusters.
-
-```bash
-cd stage2
-terraform init
-terraform apply
-```
-
-7. Obtain cluster connection information.
-
-The following command shows connection information, one cluster per line, ready to copy-paste in a shared document or spreadsheet.
-
-```bash
-terraform output -json | jq -r 'to_entries[].value.value'
-```
-
-8. Destroy clusters.
-
-```bash
-cd ..
-terraform destroy
-```
-
-9. Clean up stage2.
-
-```bash
-rm stage2/terraform.tfstate*
-```
