+# Secrets
+Secrets are managed by `agenix` (https://github.com/ryantm/agenix).
+## Creating new secrets
+1. Update `secrets/secrets.nix` with the new secret.
+
+2. When inside `./secrets`:
+```
+EDITOR=vim agenix -e "some-secret.age"
+```
+
+This will create a new secret. To view its content one can do:
+```
+EDITOR=vim agenix -d "some-secret.age" -i ~/.ssh/alex.pinwheel
+```
+
+Or use some other SSH key that is has been used to key the secret.
