 ==== Updating Existing Items ====
+To update existing items in the Library, mAirListDB will try to identify the item by one of the following columns:
+  - ID
+  - ExternalID
+  - Filename
+So if the ''ID'' column is present and contains a value, the ID will be used to identify the item; otherwise, if the ''ExternalID'' is present and contains a value, mAirList will try to identify the item by its External ID; otherwise the filename will be used. If that fails as well, it will look for an item that matches both artist and title.
+If mAirListDB is unable to identify the item in any of these ways, the item will be treated as new (see below).
+The item will be updated using the data found in the remaining columns of the file. All other fields will remain untouched. If a column contains the special value ''-'', the field will remain untouched as well.
 ==== Adding New Items ====
+CSV files can also be used to add new items to the Library. In this case, **the ''ID'' column must be empty**, and in case a value for ''ExternalID'' or ''Filename'' is given, there must be no other item in the Library with that External ID or filename already (otherwise mAirListDB would treat that line as an item update, not new item).
+When adding new **files**, the filename must be located inside any of the registered Storages.
+When no filename is given, or the ''Filename'' column is not present at all, the items will be treated as //Dummy// items.
