License preset No preset CC BY-SA 4.0 GNU Free Documentation License 1.3 CC BY-SA 4.0 adds a compact reference at the end. GFDL 1.3 skips that boilerplate and appends the full license on new pages. License subtitle / additional note With CC BY-SA this appears beneath the compact reference. With GFDL it appears at the start of the appended license. With no preset it becomes a standalone compact end note.
