+## Core Concepts
+
+### Tasking Manager Group Types
+
+- **User:** An OSM user that has logged into the Tasking Manager at least once
+    - Ex: *UW Amy Bordenave*
+- **Project:** A small area of the world that has been defined as needing mapping. Created and maintained by an organization manager
+    - Ex: *#1234 - Downtown, Seattle, WA, US: Pedestrian Infrastructure | #OpenSidewalks*
+- **Categories:** 'Labels' manually assigned to a project by the project creator based on its focus, e.g. 'disaster response' or 'pedestrian infrastructure'
+- **Campaigns:** Groups of projects which are closely related (e.g. Myanmar Earthquake 2025 campaign - which contains dozens of projects related to that particular disaster response)
+- **Teams:** Groups of OSM users created by organization managers and given varying access permissions to projects (e.g. permission to validate a project)
+- **Organizations:** Groups of projects and teams created by organization managers. E.g. Organization MSF, which has hundreds of MSF projects and has also created the MSF Validation Team
