-  Charmed Ceph FS server for non-charmed Ceph storage appliances.
+  As part of Charmed HPC, this charm deploys and manages a CephFS server proxy
+  that exposes non-charmed Ceph storage appliances as Charmed filesystems. It
+  bridges external Ceph clusters by providing authentication and connection
+  details, enabling Charmed HPC workloads to mount non-charmed CephFS shares.
 
-  Enable CephFS Client charms to mount non-charmed Ceph shares.
+  This charm integrates with the filesystem-client charm to provide mount
+  information for CephFS shares to workload charms.

 title: Filesystem Client
+summary: Charmed operator for mounting filesystems on machine charms.
+description: |
+  As part of Charmed HPC, this charm deploys and manages the filesystem client
+  responsible for mounting shared filesystems on machine charms. It handles the
+  mount lifecycle and exposes mount information to workload charms, providing
+  applications with access to exported filesystems.
 
-summary: Mount filesystems on machine charms.
+  This charm integrates with the cephfs-server-proxy, lustre-server,
+  lustre-server-proxy, and nfs-server-proxy charms to mount shared filesystems,
+  and with workload charms to expose those mounts in their machines.
