This guide aims to help researchers, data stewards, and communications staff to develop web accessible outputs for long-term deposit, such as in Zenodo. The guide contains two checklists: one for slide decks (powerpoints) and one for documents. The advice is generally software- or tool-agnostic, and contains references to external resources that may be helpful. This is version 2.0, updated with more guidance for the Google suite of software as well as new resources within the footnotes. If there are errors, please get in touch with the author.
