+Administration access
+=====================
+
+For a user with administration rights it is easy to update and save any
+dashboard configuration. Saved updates immediately take effect and become live.
+This may cause issues like:
+
+- Changes and updates made to the live configuration in Grafana can compromise
+  existing Grafana content in an unwanted, unpredicted or incompatible way.
+  Grafana as such is not version controlled, there exists one single Grafana
+  configuration per dashboard.
+- There is a risk several people can disturb each other when doing updates to
+  the same Grafana dashboard at the same time.
+
+Any change made by administrator should be careful.
