+⚠️ 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*
+```
