+These fields are pre-filled with common names but can be modified or removed:
+- `zk`, `nr_zk`, `kabel`, `dlugosc`, `data_wykonania`, `st_nr`, `obw`, `wp_short`, `plomba`
+
+### Additional Custom Fields
 - **Custom fields** override project data if they have the same name
 - Use descriptive names like `meeting_notes`, `special_instructions`, `custom_date`
 - Custom fields are available in templates as `{custom_field_name}`
 - Empty custom fields are ignored
+- All fields can be removed if not needed
 
 ### Example Custom Fields:
 - `meeting_notes`: "Please bring project documentation"
