How could the content be improved?

We currently have an AUTHORS and CITATION file that are quite out of date e.g.:

• AUTHORS only lists one author
• CITATION contains a placeholder: 'Image Processing workshop citation'

We should probably replace these with an updated CITATION.cff file, which seems to be the preferred way of storing this info now. For example, see the CITATION.cff for the carpentries lesson development training

Which part of the content does your suggestion apply to?

AUTHORS file + CITATION file
