4. Choose which type of membership you would like to create for the group. 

5. Select the setting for your group (who has permission to edit/ add content, and who can view content)

6. To add members to your group, click "Members Settings"

7. Near the bottom of the page, click "Send More Invitations".

8. Enter the e-mail addresses or Zotero usernames for the members in your group.

10. You should now see your group listed on the left. You can also access your group when you open the Zotero desktop app. Every member of your group who has permissions to edit / add resources should be able to access this group through  Zotero.org or through the desktop app.
