+# pinnwand
+These manifests provision an instance of the pinnwand service used on https://paste.pythondiscord.com.
+
+A init-service is used to download the Python Discord banner logo and save it to a volume, as pinnwand expects it to be present within the image.
+
+## Secrets & config
+This deployment expects an env var named `PINNWAND_DATABASE_URI` to exist in a secret called `pinnwand-postgres-connection`.
+All other configuration can be found in `defaults-configmap.yaml`.
