+
+---
+
+## Step 1 — Install nebula-cert
+
+```bash
+nix shell nixpkgs#nebula
+```
+
+## Step 2 — Create the CA
+
+Run once; keep `ca.key` offline/safe (do NOT commit it):
+
+```bash
+nebula-cert ca -name "thehellings.com" -out-crt ca.crt -out-key ca.key
+```
+
+Commit `ca.crt` (public) to the repo at `secrets/nebula/ca.crt`.
+Store `ca.key` securely (password manager / offline).
+
+## Step 3 — Sign host certificates
+
+For most hosts (no subnet routing):
+```bash
+nebula-cert sign -ca-crt ca.crt -ca-key ca.key \
+  -name <hostname> \
+  -ip <nebulaIp>/16 \
+  -out-crt secrets/nebula/<hostname>.crt \
+  -out-key secrets/nebula/<hostname>.key
+```
+
+For **genesis** (routes the home LAN `10.42.0.0/16`), add `-subnets`:
+```bash
+nebula-cert sign -ca-crt ca.crt -ca-key ca.key \
+  -name genesis \
+  -ip 10.157.0.2/16 \
+  -subnets '10.42.0.0/16' \
+  -out-crt secrets/nebula/genesis.crt \
+  -out-key secrets/nebula/genesis.key
+```
+
+Commit `*.crt` files (public) to the repo.
+Do NOT commit raw `*.key` files — encrypt them first (Step 4).
+
+## Step 4 — Encrypt private keys with agenix
+
+From the repo root:
+```bash
+cd nixos
+for host in linode genesis hosea isaiah jeremiah zeke exodus; do
+  agenix -e secrets/nebula/${host}.key.age < secrets/nebula/${host}.key
+  rm secrets/nebula/${host}.key   # remove plaintext key
+done
+```
+
+The `secrets/secrets.nix` file already declares the `.key.age` recipients.
+
+## Step 5 — Configure linode's public DNS / firewall
+
+- Add a DNS A record: `linode.nebula.thehellings.com` → linode's public IP
+- Open UDP port `4242` in linode's firewall / Linode Cloud Firewall rules
+
+## Step 6 — Deploy
+
+```bash
+colmena apply --on linode   # lighthouse first
+colmena apply               # rest of the fleet
+```
+
+## Verifying
+
+```bash
+# From any host, ping another by Nebula IP
+ping 10.157.0.2   # genesis
+

+## Notes
+
+- `ca.crt` is public and lives in the repo unencrypted.
+- `*.crt` (host certs) are public and live in the repo unencrypted.
+- `*.key.age` are agenix-encrypted private keys (in `secrets/nebula/`).
+- The NixOS module (`modules/nixos/nebula.nix`) references these paths directly.
+- The lighthouse (`linode`) has `isLighthouse = true` and `isRelay = true`.
+- `genesis` has `routesSubnet = "10.42.0.0/16"` which enables IP forwarding
+  and nftables masquerade so Nebula peers can reach the home LAN.
+- All other hosts have `unsafeRoutes` pointing to genesis (10.157.0.2) for
+  the 10.42.0.0/16 subnet.
