We strongly encourage you to use the second choice for documentation that should be published along with your scientific data. Please upload the document to a place with a persistent identifier. AWI people can use the ePIC system and use the corresponding handle. Others may have the possibility to use your institutional repository ,if available. If not available something like zenodo.org might work. At the end a DOI would be desirable like doi:https://doi.org/10.1093/gigascience/giz067
