+Collabora Online Group
+=====================================
+
+This submodule integrates the Group module (https://www.drupal.org/project/group) by managing group-related permissions. It allows fine-grained control over user access within groups, enabling specific permissions for Collabora content and actions based on group membership.
+
+### Requirements
+
+- Groupmedia module: https://www.drupal.org/project/groupmedia
+  - Compatible with versions 3.x and 4.x.
+
+### User permissions
+
+The module maps existing Collabora media operation permissions to the group type instances.
+
+#### Permissions:
+- "(media type): Edit any media file in Collabora"
+- "(media type): Edit own media file in Collabora"
+- "(media type): Preview published media file in Collabora"
+- "(media type): Preview own unpublished media file in Collabora"
+
+Check [Collabora Online README](/README.md#user-permissions) for more information about permissions.
+
+### Views
+
+Additionally, the submodule modifies Groupmedia view configuration to add links for Collabora operations.
