 It is likely that your `CITATION.cff` currently doesn't pass validation. The error messages you get from `cffconvert` are unfortunately a bit cryptic, but doing the following likely helps:
 
-- [ ] Fill in your given name for `given-name`
-- [ ] Check if the `family-name` key needs updating. If your last name has a name particle like `von` or `van` or `de`, use the `name-particle` key; if your name has a suffix like `Sr` or `IV`, use `name-suffix`. For details, refer to the schema description: https://github.com/citation-file-format/citation-file-format

 - [ ] Update `date-released` using the YYYY-MM-DD format.
 - [ ] Update the `doi` key with the conceptDOI for your repository (see [https://help.zenodo.org](https://help.zenodo.org/) for more information on what a conceptDOI is). If your project doesn't have a DOI yet, you can use the string `10.0000/FIXME` to pass validation.
