+description: |
+  An operator to provide self-signed X.509 certificates to your charms.
+
+  This charm relies on the `tls-certificates` charm relation interface. When a requirer charm
+  inserts a Certificate Signing Request in its unit databag, the
+  `self-signed-certificates-operator` will read it, generate a self-signed X.509 certificates and
+  inserts this certificate back into the relation data.
+
+  This charm is useful when developing charms or when deploying charms in non-production environment.
