A project is the largest unit of organization on the OSF. They could comprise multiple studies, for example, this collaborative project that the lab participated in or just a single study. The OSF site states that "A project can be an experiment, a lab group, or a paper—anything that has contributing members and files or explanatory texts/images." Setting up an OSF project is straightforward. You can follow the steps listed on the OSF website here. You will need to include a short description of the project.
