+# API Improvement Proposals: Project Charter
+
+## Article I: Purpose
+
+1. The API Improvement Proposals (AIP) project exists to help developers and
+   organizations build clear, consistent network APIs and clients by providing
+   an extensible set of design guidelines (AIPs) and an ecosystem of tools to
+   apply those rules in practice.
+2. To support this aim, the project provides and maintains tools that enrich
+   the experience of developing and using APIs that conform to the project's
+   design guidelines by generating artifacts such as client libraries and
+   documentation.
+
+## Article II: Association
+
+1. The AIP project is a project of the Cloud Native Computing Foundation. As
+   such, it accepts the [CNCF Code of Conduct][0].
+
+## Article III: Steering Committee
+
+1. The AIP project shall be governed by a steering committee, comprising at
+   least five representatives from at least five distinct organizations.
+2. No more than one third of the committee shall represent or be employed by
+   the same organization.
+   1. In the event that ambiguities arise regarding what constitutes "the same
+      organization," a vote of the committee shall decide. Any members from the
+      organizations under consideration may deliberate, but shall recuse
+      themselves from the vote.
+3. Membership on the steering committee shall be by invitation of the current
+   steering committee. The steering committee shall meet at least once annually
+   to consider the addition, removal, or replacement of members.
+4. The members of the steering committee shall be maintained in a
+   MAINTAINERS.md file in the
+   [primary AIP GitHub repository](https://github.com/aip-dev/aip).
+5. Steering committee members accept the following responsibilities:
+   1. Ownership of the charter, vision, and direction of the AIP project.
+   2. Regular attendance and participation at stated committee meetings.
+   3. Contribution of design guidance or code as appropriate, and reviewing the
+      contributions of others.
+6. Steering committee members who are unable or unwilling to continue to
+   perform the responsibilities described above may voluntarily step down from
+   the committee or may be removed from the steering committee without
+   prejudice. Former committee members will be designated as "emeritus" in the
+   maintainers list.
+7. The steering committee may appoint additional maintainers, to whom it may
+   delegate tasks as necessary.
+
+## Article IV: Source of Truth
+
+1. The AIP GitHub repositories are the source of truth for everything in the
+   project, including both code and guidelines.
+
+## Article V: Meetings & Voting
+
+1. The steering committee shall hold a regular meeting on a cadence of its
+   choosing, and shall keep minutes of said meetings in a GitHub repository set
+   aside for that purpose, which shall be accessible by all steering committee
+   members.
+   1. Meetings and minutes may be public or private, at the discretion of the
+      steering committee.
+2. The steering committee ordinarily operates by consensus, and recording votes
+   for each decision is not required (but the decision should be recorded in
+   the minutes). When possible, decisions and voting shall be done using GitHub
+   issues for transparency.
+3. In the event that a vote is required, an email shall be sent to each
+   steering committee explaining the issue in question and allowing at least 10
+   business days for voting. The specifics of how elections are handled are at
+   the discretion of the steering committee.
+
+## Article VI: Amendment
+
+This charter may be amended by a two-thirds supermajority of the steering
+committee, after conducting an vote as described in V§3.
