A digital object identifier (DOI) is a character string used to uniquely identify an object such as an electronic document. Learn more about digital object identifiers.

Thanks to Scientific Protocols integration with Zenodo when you publish your protocol you will automatically receive a DOI. The DOI will be added as a markdown compatible button at the end of your protocol.

Because the button is part of your protocols markdown you can move it to a different location in your protocol or remove it entirely if you want to. Simply edit your protocol and move the buttons markdown snippet to a new location in your protocol. The following is a sample of the DOI buttons markdown snippet.
