Using this template in lists (i.e. using * {{self|cc-by-3.0}}) is discouraged. Doing so will lead to lint errors.
This template accepts licenses as unnamed parameters, which should be the names of image license templates, and displays them as options to choose between in a multi-license. If the image was not uploaded by its author, you can change "I" at the start of the template to another name by setting the author= parameter.
The optional migration= parameter corresponds to keywords in the {{License migration}} template series and is used to track the license update process for GFDL images.
Here are 4 examples of multi-license templates along with links to their component parts:
