The Wikimedia Foundation is the nonprofit that hosts Wikipedia and our other free knowledge projects. We want to make it easier for everyone to share what they know. To do this, we keep Wikipedia and Wikimedia sites fast, reliable, and available to all. We protect the values and policies that allow free knowledge to thrive. We build new features and tools to make it easy to read, edit, and share from the Wikimedia sites. Above all, we support the communities of volunteers around the world who edit, improve, and add knowledge across Wikimedia projects.

One of the ways we support this goal is through providing essential infrastructure and support to a growing network of Wikimedia self-governance committees and groups who enable the communities to govern themselves within the framework set by Foundation policies. This role, housed in the Committee...
