+# Adding a new Kubernetes Version
+
+## `pinniped's ci branch`
+
+- [ ] Update `dockerfile-builders` pipeline
+- [ ] Update `pull-requests` pipeline
+- [ ] Update `main` pipeline
+
+## `pinniped`
+
+- [ ] Bump all golang dependencies (especially the `k8s.io` dependencies to use the new minor version).
+  - [ ] Be sure to verify that everything compiles and unit tests pass locally. This is probably a good starting point.
+```shell
+./hack/update-go-mod/update-go-mod.sh
+./hack/module.sh unit
+./hack/prepare-for-integration-tests.sh
+```
+- [ ] Log in to github as pinniped-ci-bot, then go to [this page](https://github.com/pinniped-ci-bot?tab=packages) and change the settings for the new `k8s-code-generator-1.*` image to be publicly visible
+- [ ] Add the new K8s version to `hack/lib/kube-versions.txt` and run code generation.
+
+## General Tasks
+
+- [ ] Consider dropping support for any older versions of Kubernetes
+- [ ] Create stories or chores to take advantage of features in the new Kubernetes version

+
+# Release checklist
+
+- [ ] Ensure that Pinniped's dependencies have been upgraded, to the extent desired by the team (refer to the diff output from the latest run of the [all-golang-deps-updated](https://ci.pinniped.broadcom.net/teams/main/pipelines/security-scan/jobs/all-golang-deps-updated/) CI job)
+  - [ ] If you are updating golang in Pinniped, be sure to update golang in CI as well.  Do a search-and-replace to update the version number everywhere in the pinniped `ci` branch.
+  - [ ] If the Fosite library is being updated and the format of the content of the Supervisor's storage Secrets are changed, or if any change to our own code changes the format of the content of the Supervisor's session storage Secrets, then be sure to update the `accessTokenStorageVersion`, `authorizeCodeStorageVersion`, `oidcStorageVersion`, `pkceStorageVersion`, `refreshTokenStorageVersion`, variables in files such as `internal/fositestorage/accesstoken/accesstoken.go`.  Failing tests should signal the need to update these values.
+  - [ ] For go.mod direct dependencies that are v2 or above, such as `github.com/google/go-github/vXX`, check to see if there is a new major version available. Try using `hack/update-go-mod/update-majors.sh`.
+  - [ ] Evaluate all `replace` directives in the `go.mod` file. Are those versions up-to-date? Can any `replace` directives be removed?
+  - [ ] Evaluate all overrides in the `hack/update-go-mod/overrides.conf` file. Are those versions up-to-date? Can those overrides be removed?
+- [ ] Ensure that Pinniped's codegen is up-to-date with the latest Kubernetes releases by making sure this [file](https://github.com/vmware/pinniped/blob/main/hack/lib/kube-versions.txt) is updated compared to the latest releases listed [here for active branches](https://kubernetes.io/releases/) and [here for non-active branches](https://kubernetes.io/releases/patch-releases/#non-active-branch-history)
+- [ ] Ensure that the `k8s-code-generator` CI job definitions are up-to-date with the latest Go, K8s, and `controller-gen` versions
+- [ ] All relevant feature and docs PRs are merged
+- [ ] The [main pipeline](https://ci.pinniped.broadcom.net/teams/main/pipelines/main) is green, up to and including the `ready-to-release` job. Check that the expected git commit has passed the `ready-to-release` job.
+- [ ] Manually trigger the jobs `run-int-misc`, `run-int-cloud-providers`, and `run-int-k8s-versions` in the main pipeline to run other pre-release tests. Depending on the number of Concourse workers, you may need to run these one at a time.
+- [ ] Optional: a blog post for the release is written and submitted as a PR but not merged yet
+- [ ] All merged user stories are accepted (manually tested)
+- [ ] Only after all stories are accepted, manually trigger the `release` job to create a draft GitHub release
+- [ ] Manually edit the draft release notes on the [GitHub release](https://github.com/vmware/pinniped/releases) to describe the contents of the release, using the format which was automatically added to the draft release
+- [ ] Publish (i.e. make public) the draft release
+- [ ] After making the release public, the jobs in the [main pipeline](https://ci.pinniped.broadcom.net/teams/main/pipelines/main) beyond the release job should auto-trigger, so check to make sure that they passed
+- [ ] Edit the blog post's date to make it match the actual release date, and merge the blog post PR to make it live on the website
+- [ ] Publicize the release via tweets, etc.
+- [ ] Close this issue

+
+It can sometimes be convenient to use GoLand to run an integration test. For example, this allows using the

+
+Note that the output of `hack/prepare-for-integration-tests.sh` says:
+
+```bash
+# Using GoLand? Paste the result of this command into GoLand's run configuration "Environment".
+#    hack/integration-test-env-goland.sh | pbcopy
+```
+
+After using `hack/prepare-for-integration-tests.sh`, run `hack/integration-test-env-goland.sh | pbcopy` as instructed. Then:
+
+1. Select and run an integration test within GoLand. It will fail complaining about missing env vars.
+1. Pull down the menu that shows the name of the test which you just ran in the previous step, and choose "Edit Configurations...".
+1. In the "Environment" text box for the run configuration of the integration test that you just ran,
+   paste the results of `hack/integration-test-env-goland.sh | pbcopy`.
+1. Apply, and then run the integration test again. This time the test will use the environment variables provided.
+
+Note that if you run `hack/prepare-for-integration-tests.sh` again, then you may need to repeat these steps.
+Each run of `hack/prepare-for-integration-tests.sh` can result in different values for some of the env vars.

+# Pinniped Governance
+
+This document defines the project governance for Pinniped.
+
+# Overview
+
+**Pinniped** is committed to building an open, inclusive, productive and self-governing open source community focused on
+building authentication services for Kubernetes clusters. The community is governed by this document which defines how
+all members should work together to achieve this goal.
+
+# Code of Conduct
+
+The Pinniped community abides by this
+[code of conduct](https://github.com/vmware/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:** Responsible for the overall health and direction of the project. They are the final reviewers of PRs
+  and responsible for Pinniped releases.
+
+# 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/pinniped/blob/main/CODE_OF_CONDUCT.md).
+
+# 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.
+
+## Supermajority
+
+A supermajority is defined as two-thirds of members in the group. A supermajority of maintainers is required for certain
+decisions as outlined in this document. A supermajority vote is equivalent to the number of votes in favor being at
+least twice the number of votes against. A vote to abstain equals not voting at all. For example, if you have 5
+maintainers who all cast non-abstaining votes, then a supermajority vote is at least 4 votes in favor. 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.
+
+## Lazy Consensus
+
+To maintain velocity in Pinniped, the concept of [Lazy Consensus](http://en.osswiki.info/concepts/lazy_consensus) is
+practiced.
+
+Other maintainers may chime in and request additional time for review, but should remain cognizant of blocking progress
+and abstain from delaying progress unless absolutely needed. The expectation is that blocking progress is accompanied by
+a guarantee to review and respond to the relevant action in short order.
+
+Lazy consensus does not apply to the process of:
+
+* Removal of maintainers from Pinniped
+
+## Updating Governance
+
+All substantive changes in Governance, including substantive changes to the proposal process, require a supermajority
+agreement by all maintainers.
+
+# Proposal Process
+
+The proposal process is defined in [proposals/README.md](proposals/README.md).

 ## Overview
 
 Pinniped provides identity services to Kubernetes.
 
-Pinniped allows cluster administrators to easily plug in external identity
-providers (IDPs) into Kubernetes clusters. This is achieved via a uniform
-install procedure across all types and origins of Kubernetes clusters,
-declarative configuration via Kubernetes APIs, enterprise-grade integrations
-with IDPs, and distribution-specific integration strategies.
+- Easily plug in external identity providers into Kubernetes clusters while offering a simple install and configuration experience. Leverage first class integration with Kubernetes and kubectl command-line.
+- Give users a consistent, unified login experience across all your clusters, including on-premises and managed cloud environments.
+- Securely integrate with an enterprise IDP using standard protocols or use secure, externally managed identities instead of relying on simple, shared credentials.
 
-### Example use cases
-
-* Your team uses a large enterprise IDP, and has many clusters that they
-  manage. Pinniped provides:
-  * Seamless and robust integration with the IDP
-  * Easy installation across clusters of any type and origin
-  * A simplified login flow across all clusters
-* Your team shares a single cluster. Pinniped provides:
-  * Simple configuration to integrate an IDP
-  * Individual, revocable identities
-
-### Architecture
-
-The Pinniped Supervisor component offers identity federation to enable a user to
-access multiple clusters with a single daily login to their external IDP. The
-Pinniped Supervisor supports various external [IDP
-types](https://github.com/vmware-tanzu/pinniped/tree/main/generated/1.20#k8s-api-idp-supervisor-pinniped-dev-v1alpha1).
-
-The Pinniped Concierge component offers credential exchange to enable a user to
-exchange an external credential for a short-lived, cluster-specific
-credential. Pinniped supports various [authentication
-methods](https://github.com/vmware-tanzu/pinniped/tree/main/generated/1.20#authenticationconciergepinnipeddevv1alpha1)
-and implements different integration strategies for various Kubernetes
-distributions to make authentication possible.
-
-The Pinniped Concierge can be configured to hook into the Pinniped Supervisor's
-federated credentials, or it can authenticate users directly via external IDP
-credentials.
-
-To learn more, see [architecture](https://pinniped.dev/docs/background/architecture/).
+To learn more, please visit the Pinniped project's website, https://pinniped.dev.

+## 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.
 
-### 
-**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/pinniped#discussion).
+[Contributions](https://github.com/vmware/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/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.
-
-
-### 
-**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?**
-
-Please open an issue to track any initiative on the roadmap of Pinniped (usually driven by new feature requests). We will work with and rely on our community to focus our efforts to improve Pinniped.
-
-
-### 
-**Current Roadmap**
-
-The following table includes the current roadmap for Pinniped. If you have any questions or would like to contribute to Pinniped, please attend a [community meeting](https://github.com/vmware-tanzu/pinniped/blob/main/CONTRIBUTING.md#meeting-with-the-maintainers) to discuss with our team. If you don't know where to start, we are always looking for contributors that will help us reduce technical, automation, and documentation debt. Please take the timelines & 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 attend community meetings to get updated status information, or help us deliver that feature by contributing to Pinniped.
