+== How to change System Configuration
+
+The System Configuration can be modified in a couple of ways:
+
+* In GUI choose *System* in the main menu and then the relevant section.
+This supports many common configuration changes, but not all.
+
+* In GUI choose *Repository Objects*/*All Objects* in the main menu - *SystemConfiguration* object appears in the list.
+Click on it, edit the XML as needed and then click the *Save* button to apply the changes.
+
+* Use xref:/midpoint/tools/studio/[MidPoint Studio] - download the current system configuration first, then change it and upload it back.
+
+GUI related changes require logout/login of the user.
