+[code of conduct](https://github.com/vmware-tanzu/pinniped/blob/main/CODE_OF_CONDUCT.md).
 
 # Community Roles
 
 * **Users:** Members that engage with the Pinniped community via any medium (Slack, GitHub, mailing lists, etc.).
-* **Contributors:** Do regular contributions to the Pinniped project (documentation, code reviews, responding to issues, participating in proposal discussions, contributing code, etc.).

 # Maintainers
-New maintainers must be nominated by an existing maintainer and must be elected by a supermajority of existing maintainers. Likewise, maintainers can be removed by a supermajority of the existing maintainers or can resign by notifying one of the maintainers.
 
-**Note:** If a maintainer leaves their employer they are still considered a maintainer of Pinniped, unless they voluntarily resign. Employment is not taken into consideration when determining maintainer eligibility unless the company itself violates our [Code of Conduct](https://github.com/vmware-tanzu/pinniped/blob/main/CODE_OF_CONDUCT.md).

-# Supermajority
-A supermajority is defined as two-thirds of members in the group. A supermajority of Maintainers is required for certain decisions as outlined above. A supermajority vote is equivalent to the number of votes in favor of being at least twice the number of votes against. For example, if you have 5 maintainers, a supermajority vote is 4 votes. Voting on decisions can happen on the mailing list, GitHub, Slack, email, or via a voting service, when appropriate. Maintainers can either vote "agree, yes, +1", "disagree, no, -1", or "abstain". A vote passes when supermajority is met. An abstain vote equals not voting at all.
+**Note:** If a maintainer leaves their employer they are still considered a maintainer of Pinniped, unless they
+voluntarily resign. Employment is not taken into consideration when determining maintainer eligibility unless the

 # Decision Making
-Ideally, all project decisions are resolved by consensus. If impossible, any maintainer may call a vote. Unless otherwise specified in this document, any vote will be decided by a supermajority of maintainers.
 
----
-# Proposal Process 
-The proposal process is currently being worked on. No formal process is available at this time. You may reach out to the maintainers in the Kubernetes Slack Workspace within the [#pinniped](https://kubernetes.slack.com/archives/C01BW364RJA) channel or on the [Pinniped mailing list](project-pinniped@googlegroups.com) with any questions you may have or to send us your proposals.
+Ideally, all project decisions are resolved by consensus. If impossible, any maintainer may call a vote. Unless

----
-# Lazy Consensus
-To maintain velocity in Pinniped, the concept of [Lazy Consensus](http://en.osswiki.info/concepts/lazy_consensus) is practiced. Ideas and / or proposals should be shared by maintainers via GitHub. Out of respect for other contributors, major changes should also be accompanied by a ping on the Kubernetes Slack in [#Pinniped](https://kubernetes.slack.com/archives/C01BW364RJA) or a note on the [Pinniped mailing list](project-pinniped@googlegroups.com) as appropriate. Author(s) of proposals for major changes will give a time period of no less than five (5) working days for comment and remain cognizant of popular observed world holidays.
+## Supermajority
 
-**What constitutes the need for a proposal?**
-If there is significant risk with a potential feature or track of work (such as complexity, cost to implement, product viability, etc.), then we recommend creating a proposal for feedback and approval. If a potential feature is well understood and doesn't impose risk, then we recommend a **standard GitHub issue** to clarify the details.

+## Pinniped Project Roadmap
 
-## **Pinniped Project Roadmap**
+### About this document
 
+This document provides a high-level overview of the next big features the maintainers are planning to work on. This
+should serve as a reference point for Pinniped users and contributors to understand where the project is heading, and
+help determine if a contribution could be conflicting with a longer term plan.
+The [Pinniped project backlog](https://github.com/orgs/vmware-tanzu/projects/43/) is prioritized based on this roadmap,
+and it provides a more granular view of what the maintainers are working on a day-to-day basis.
 
-### 
-**About this document**
+### How to help
 
-This document provides a link to the[ Pinniped Project issues](https://github.com/vmware-tanzu/pinniped/issues) list that serves as the up to date description of items that are in the Pinniped release pipeline. Most items are gathered from the community or include a feedback loop with the community. This should serve as a reference point for Pinniped users and contributors to understand where the project is heading, and help determine if a contribution could be conflicting with a longer term plan.
+Discussion on the roadmap is welcomed. If you want to provide suggestions, use cases, and feedback to an item in the
+roadmap, please reach out to the maintainers using one of the methods described in the project's
+[README.md](https://github.com/vmware-tanzu/pinniped#discussion).
+[Contributions](https://github.com/vmware-tanzu/pinniped/blob/main/CONTRIBUTING.md) to Pinniped are also welcomed.
 
+### How to add an item to the roadmap
 
-### 
-**How to help?**
+One of the most important aspects in any open source community is the concept of proposals. Large changes to the
+codebase and / or new features should be preceded by
+a [proposal](https://github.com/vmware-tanzu/pinniped/tree/main/proposals) in our repo.
+For smaller enhancements, you can open an issue to track that initiative or feature request.
+We work with and rely on community feedback to focus our efforts to improve Pinniped and maintain a healthy roadmap.
 
-Discussion on the roadmap can take place in threads under [Issues](https://github.com/vmware-tanzu/pinniped/issues) or in [community meetings](https://github.com/vmware-tanzu/pinniped/blob/main/CONTRIBUTING.md#meeting-with-the-maintainers). Please open and comment on an issue if you want to provide suggestions and feedback to an item in the roadmap. Please review the roadmap to avoid potential duplicated effort.
+### Current Roadmap
 
+The following table includes the current roadmap for Pinniped. Please take the timelines and dates as proposals and
+goals. Priorities and requirements change based on community feedback, roadblocks encountered, community contributions,
+etc. If you depend on a specific item, we encourage you to reach out for updated status information, or help us deliver
+that feature by [contributing](https://github.com/vmware-tanzu/pinniped/blob/main/CONTRIBUTING.md) to Pinniped.
 
-### 
-**Need an idea for a contribution?**
-
-We’ve created an [Opportunity Areas](https://github.com/vmware-tanzu/pinniped/discussions/483) discussion thread that outlines some areas we believe are excellent starting points for the community to get involved. In that discussion we’ve included specific work items that one might consider that also support the high-level items presented in our roadmap.

-**How to add an item to the roadmap?**
