If you mean how to publish in ResearchGate, note that ResearchGate is neither a journal nor a publisher, you cannot "publish" an article here. It is a platform for articles published in journals, or to present unpublished texts, data etc. See also "Is ResearchGate a publisher?" in https://help.researchgate.net/hc/en-us/articles/14292596164753. And see this help page for instructions how to add published or unpublished research to your ResearchGate profile: https://help.researchgate.net/hc/en-us/articles/14293005132305-How-to-add-research

To publish an article, you need to first choose a suitable journal or platform, prepare your manuscript according to their guidelines, and then submit it through their designated system. After submission, the article will undergo a review process, and if accepted, it will be published.How do I get my first article published?

Does ResearchGate publishes articles, too? Thank you so much Abu-Hussein and everyone on this chat.

Thank you, Wolfgang.

Dear Rosita Cortizo,

No, ResearchGate does not publish articles. See the second part of my first answer. You may upload research results here, but this will not be regarded as a publication.
