I am writin to you to ask the procedures that I have to take for publishin an article in your jouranl "Resaechgate" and get a DOI after publishing article. Thus, what can I do?
To Mateso Bashingwa: In the case of RG, DOIs can be generated for most of your unpublished work. As publications classified as article, book, chapter, patent, cover page, poster, and conference paper are considered to have been published elsewhere, DOIs cannot be generated for these types of research.
Next, borrowing from Rob Keller: The best and most easy way to create a DOI for a paper of a journal that don't assign doi number or chapters of previously published books without a doi etc. is Zenodo: https://zenodo.org/

Please note that ResearchGate (RG) is not a journal. When you upload a text, this will not become a publication. RG is just a platform for collecting research published elsewhere or for presenting preprints, data and other unpublished texts.
