### 💡 [Do not skip] Creating the terraform.tfvars file
1. Create a project in your [Hetzner Cloud Console](https://console.hetzner.cloud/), and go to **Security > API Tokens** of that project to grab the API key. Take note of the key! ✅
2. Either, generate a passphrase-less ed25519 ssh key-pair for your cluster, unless you already have one that you'd like to use. Take note of the respective paths of your private and public keys! Or for a key-pair with passphrase or a device like a Yubikey, make sure you have got an SSH agent running and your key is loaded (`ssh-add -L` to verify) and set `private_key = null`. ✅

Or, for a key-pair with passphrase or a device like a Yubikey, make sure you have got an SSH agent running and your key is loaded (`ssh-add -L` to verify) and set `private_key = null` in the following step. ✅
3. Copy `terraform.tfvars.example` to `terraform.tfvars`, and replace the values from steps 1 and 2. ✅
4. (Optional) There are other variables in `terraform.tfvars` that could be customized, like Hetzner region, and the node counts and sizes.
