+short_description: Retrieves ACME Renewal Information (ARI) for a certificate
+description:
+  - "Allows to retrieve renewal information on a certificate obtained with the
+     L(ACME protocol,https://tools.ietf.org/html/rfc8555)."
+  - "This module only works with the ACME v2 protocol, and requires the ACME server
+     to support the ARI extension (U(https://datatracker.ietf.org/doc/draft-ietf-acme-ari/)).
+     This module implements version 3 of the ARI draft."
