+Encrypted with [sops](https://github.com/getsops/sops) using the
+host's age key.
+
+## First-time setup on the server
+
+1. Generate an age key for the host:
+   ```
+   sudo mkdir -p /var/lib/sops-nix
+   sudo age-keygen -o /var/lib/sops-nix/key.txt
+   sudo chmod 600 /var/lib/sops-nix/key.txt
+   ```
+2. Read the public key:
+   ```
+   sudo grep "public key" /var/lib/sops-nix/key.txt
+   ```
+3. On a workstation, put that public key into `.sops.yaml` at
+   the repo root and encrypt `tide.yaml.example` into
+   `tide.yaml`.
+
+`tide.yaml` is encrypted and committed. `tide.yaml.example` is
+the plaintext template.
