+# How to Enable Cloud Storage
+# ---------------------------
+# By default the only data storage enabled for this space is local. In the case
+# of a space reset, all data will be lost. To enable permanent storage, you
+# must enable a cloud storage connector. We also strongly recommend enabling
+# configuration persistence to preserve project data, annotations, and user
+# settings. Choose the appropriate cloud connector and configure the secrets
+# for it.
