 # Indico Operator
 
 A Juju charm deploying and managing Indico on Kubernetes. Indico is an
-open-source tool for event organisation, archival and collaboration.
-
-This charm simplifies initial deployment and "day N" operations of Indico
-on Kubernetes, such as scaling the number of instances, integration with SSO,
-access to S3 for redundant file storage and more. It allows for deployment on
+open-source tool for event organisation, archival and collaboration. It allows for deployment on
 many different Kubernetes platforms, from [MicroK8s](https://microk8s.io) to
 [Charmed Kubernetes](https://ubuntu.com/kubernetes) to public cloud Kubernetes
 offerings.
 
-As such, the charm makes it easy for those looking to take control of their own
-events management system whilst keeping operations simple, and gives them the
-freedom to deploy on the Kubernetes platform of their choice.
+Like any Juju charm, this charm supports one-line deployment, configuration, integration, scaling, and more. For Charmed Indico, this includes:
+  - Scaling
+  - Integration with SSO
+  - Integration with S3 for redundant file storage
 
-For DevOps or SRE teams this charm will make operating Indico simple and
-straightforward through Juju's clean interface. It will allow easy deployment
-into multiple environments for testing of changes, and supports scaling out for
-enterprise deployments.
+For information about how to deploy, integrate, and manage this charm, see the Official [Indico Operator Documentation](https://charmhub.io/indico/docs).
