+# Linkerd Governance
+
+This document defines project governance for Linkerd.
+
+## Roles
+
+There are two roles that convey decision-making powers: maintainer and
+super-maintainer. MAINTAINERS.md defines the membership of these roles.
+
+## Expectations
+
+Maintainers are responsible for one or more components, and are expected to
+contribute code, field incoming PRs, triage issues, proactively fix bugs, and
+generally perform maintainance tasks for these components.
+
+Super-maintainers are responsible for the project as a whole, and are expected
+to guide general project direction as well as being the final reviewer on PRs.
+
+## Decisionmaking
+
+Ideally, all project decisions are resolved by consensus. If this is not
+possible, maintainers may call a vote. Unless otherwise specified in this
+document, the vote will be decided by a simple majority in which each
+super-maintainer receives two votes and each maintainer receives one vote.
+
+## Changes in Maintainership
+
+New maintainers must be proposed by an existing maintainer and must be elected
+by a 2/3 majority organization vote. Maintainers can be removed by a 2/3
+majority organization vote.
+
+Super-maintainers must be proposed by an existing super-maintainer and must be
+elected by a 2/3 majority organization vote. Super-maintainers can be removed
+by a 2/3 majority organization vote.
+
+## GitHub Project Administration
+
+Maintainers will be added to the linkerd GitHub organization, and be made an
+owner of the GitHub organization.
+
+## Approving PRs
+
+All PRs must receive approval from at least one super maintainer before merge.
+
+## Changes in Governance
+
+All changes in Governance require a 2/3 majority organization vote.
