-Code based on [github.com/mockersf/concourse-slack-notifier](https://github.com/mockersf/concourse-slack-notifier).
-Currently, only the [persistent storage solution](https://github.com/caronc/apprise-api#persistent-storage-solution) is supported (because that's what I use).

-```yaml
-resource_types:
-- name: apprise
-  type: registry-image
-  source:

-```
-
-## Source Configuration
-
-- `host`: _Required_. Base Apprise host URL.
-- `key`: _Required_. Notification key.
-
-## Behaviour
-
-`check`: No operation.
-
-`in`: No operation.
-
-`out`: Send a message via Apprise.
-
-### Parameters
