+# Governance
+
+The Gazebo project, a project under the Open Source Robotics Foundation, is
+managed by the Open Source Robotics Alliance (OSRA). The OSRA-appointed
+Technical Governance Committee provides oversight of the project, while the
+Project Management Committee is responsible for day-to-day operations. This
+document outlines these entities and their respective roles and
+responsibilities. For further information, please refer to
+[OSRA website](https://osralliance.org/how-it-works/).
+
+## Open Source Robotics Alliance (OSRA)
+
+The Open Source Robotics Foundation (OSRF) established the Open Source Robotics
+Alliance (OSRA) to enhance the governance of its open-source projects including
+Gazebo. Inspired by the success of organizations like The Linux Foundation and
+the Eclipse Foundation, OSRA aims to provide funding, encourage greater
+community involvement, and ensure the long-term stability of these projects. The
+OSRA has a Technical Governance Committee that oversees the technical aspects of
+the projects.
+
+## Technical Governance Committee (TGC)
+
+The TGC provides guidance and oversight to each of the projects. Its
+responsibilities include approving proposed activities of each Project
+Management Committee (PMC), approving Project Leader nominations, and reporting
+to the OSRF Board on the activities of the OSRA and status of each project.
+
+## The Gazebo Project Management Committee (PMC)
+
+The Gazebo PMC is responsible for the day-to-day management of the Gazebo
+project including setting the project’s roadmap, coordinating development
+activities from individual contributors, and facilitating community engagement.
+The PMC is also responsible for electing the Project Leader and approving PMC
+member and committer nominations. The PMC consists of the Project Leader,
+Members (individuals with full voting rights), a Supporting Individual
+Representative, and the Chair of the TGC.
+
+## Committers
+
+The Gazebo project also has committers. These are individuals who have commit
+access to one or more of the Gazebo repositories and help the PMC maintain the
+project by contributing code, reviewing pull requests, and responding to issues,
+etc. While committers typically don't have voting rights within the PMC and
+aren't considered PMC members, it's possible to hold both roles. Conversely, all
+PMC members are required to be committers.
+
+## Current Gazebo PMC Constituents
+
+The Gazebo PMC currently consists of the following individuals:
