+**If you have any questions or problems while using the image, please ask for assistance on the Help Forum first (https://help.nextcloud.com)**.
+
+Also, most Nextcloud Server matters are covered in the [Nextcloud Admin Manual](https://docs.nextcloud.com/server/latest/admin_manual/) which is routinely updated.
+
+If you believe you've found a bug (or have an enhancement idea) in the image itself, please [search for already reported bugs and enhancement ideas](https://github.com/nextcloud/docker/issues). If there is an existing open issue, you can either add to the discussion there or upvote to indicate you're impacted by (or interested in) the same issue. If you believe you've found a new bug, please create a new Issue so that others can try to reproduce it and remediation can be tracked.
