+One administrator, @ntnsndr, holds ultimate decision-making power over the project. This is a temporary arrangement while we build trust as a community and adopt a more inclusive structure.
+
+* **Autocracy** The administrator holds ultimate decision-making power in the community.
+    * **Executive** The administrator is responsible for implementing—or delegating implementation of—policies and other decisions.
+    * **Lobbying** If participants are not happy with the administrator's leadership, they may voice their concerns or leave the community.
+* **Do-ocracy** Those who step forward to do a given task can decide how it should be done, in ongoing consultation with each other and the administrator.
+    * **Membership** Participation is open to anyone who wants to contribute. The administrator can remove misbehaving participants at will for the sake of the common good.
+* **Code of Conduct** Participants are expected to abide by the Contributor Covenant (contributor-covenant.org).
+* **Ownership** This is a project of the Media Enterprise Design Lab at the University of Colorado Boulder and is owned by the university.
