Register an account on OSF, create a "project" page, and pre-register a study using the AsPredicted pre-registration template. This can be a pre-registration for the project you plan to do for this subject, for a project you plan to do for another subject or for your dissertation, for an imaginary project you won't ever do, or it can even be a fake "pre"-registration for a project you have already completed. Make sure you make your project page and your pre-registration public.
