 Adding contributors to a project allows credit to be given to those who have worked on the project and allows them to make changes. Admins on a project can add contributors by visiting the sharing tab in the green navigation bar. Click the green add button and a pop-up will appear where you can search for the person to add. If they have an OSF account, their name will appear and you can add them and select their privileges. If you do not have an OSF account, you can provide them as an unregistered user and they will be notified by email. Each contributor will have access to the same files, know the state of the project, and you can pick which components they have access to. The contributor permissions are the rules that govern who can see and edit a project. When a project is made, the creator is automatically the administrator, meaning they can add other people and make changes to the project. The admin can add contributors and make them administrators as well, or they can assign the other contributors read and write or even just read privileges. As you might expect, having reading privileges means that you can see any project or component on which you are listed as a contributor. Reading and writing privileges means that you can see and edit any project or component that you're added to. However, you cannot add or remove contributors, delete components, or register projects. One perk of being an admin on a project is that you can change the order that the contributors are listed with a simple drag and drop. Admins can also remove the visibility from a contributor to remove them from the project citation.
