+
+## Default roles assigned in ELN
+
+When a user is registered via the ELN interface, a *Space* (folder) with
+the name of the user is automatically created under the Lab Notebook
+main menu. The user is also assigned some default roles:
+
+1.  *Space admin* of the *Space* created for him/her under the notebook.
+2.  *Space user of* the Inventory *Spaces* (MATERIALS, METHODS by
+    default), the STOCK\_CATALOG and the STORAGE *Spaces*.
+3.  *Space Observer* of the STOCK\_ORDERS, ELN\_SETTINGS and
+    PUBLICATIONS S*paces*.
+
+
+Modification to default rights can be granted by an *Instance admin*
+from the *admin UI*, as explained below.
