Thanky hanna, looks fine, I would just combine these two options to be more flexible.

otherwise approved

[ahms5]

maybe we can combine year and holder to copyright_statement. This will be more flexible, because in some packages we have custum statements, e.g. sparpy
for copyright_statement we could make a default like {{current_year}}, {{author}}

[ahms5]

or a better default could be {{current_year}}, The pyfar developers, because this is most common

Thank you for the review! I'm not sure I know how to combine the parameters... Do you mean something like:

copyright_statement:
    type: str
    help: ""
    default:
        author: The pyfar developers
        year: {{current_year}}

?

sth like this

Suggested change

	copyright_holder:
	type: str
	help: "Who is the copyright holder, for example, yourself or your organization? Used in copyright statements."
	default: "{{ git_username }}"
	year:
	type: str
	help: "What is the starting year of the project? Used in copyright statements."
	default: "{{ '%Y' | strftime }}"
	copyright_statement:
	type: str
	help: "What is the copyright statement. Usually it is sth like publication year, name of copyright holder."
	default: "{{ '%Y' | strftime }}, The pyfar developers"

[ahms5]

Suggested change

	default: "{{ '%Y' | strftime }}, The pyfar developers"
	default: "{{ '%Y' | strftime }}, {{ authors }}"

we can add an other fiedl for authors, since this will be need somewhere else.
