 Roadmap
 =======
 
-The roadmap items are categorised into themes based on the larger goals we want to achieve with cert-manager.
-
-
-While this is a summary of the direction we want to go we welcome all PRs, even if they don't fall under any of the roadmap items
-listed here. We unfortunately can't merge every change, and if you're looking to contribute a new feature you might want to
-check the [contributing guide](https://cert-manager.io/docs/contributing/) on the cert-manager website.
-
-
-### Integration with other projects in the cloud-native landscape
-
-cert-manager should be able to deliver and manage X.509 certificates to popular
-projects in the cloud-native ecosystem.
-
-- Service Mesh Integration: While we have good Istio and Open Service Mesh integration, expand to other projects such as Linkerd, cilium
-
-### Adoption of upstream APIs
-
-Continue to support latest APIs for upstream K8s and related SIGs.
-
-- Kubernetes APIs: keep up to date with Kubernetes API changes and release cadence
-- CSR API: support the sig-auth CSR API for certificate requests in kubernetes
-- [Trust Anchor Sets](https://github.com/kubernetes/enhancements/pull/3258)
-- Gateway API
-
-### Extensibility
-
-Widen the scope of integrations with cert-manager.
-
-- EST support: support a standard for ACME-like issuance within an enterprise
-- External DNS plugin: enable ACME DNS01 requests to be completed using external-dns
-- Improve external issuer development experience: documentation and examples for people developing external issuers
-
-### PKI lifecycle
-
-Enable best-practice PKI management with cert-manager.
-
-- Handle CA certs being renewed: deal with the cases where the CA cert is renewed and allow for all signed certs to be renewed
-- Make cert-manager a viable way to create and manage private PKI deployments at scale
-- Trust root distribution: handle distributing all trust roots within a cluster, solving trust for private and public certificates
-
-See also [trust-manager](https://cert-manager.io/docs/projects/trust/) for more on trust distribution.
-
-### End-user experience
-
-- Graduate alpha / beta features in good time:
-  - SIG-Auth CSR API support
-  - SIG-Network Gateway API support
-- Easier diagnosis of problems: improve cert-manager output to make status clearer, and provide tools to aid debugging
-- Improve the new contributor experience
-
-### Developer experience
-
-- Better user experience for installation, operation and use with applications
-- Zero test flakiness and increased testing confidence
-- Improve release process by adding more automation
-
-### Shrinking Core
-
-Minimise the surface area of cert-manager, reducing attack surface, binary size, container size and default deployment complexity
-
-- Move "core" issuers with dependencies (ACME, Vault, Venafi) into external issuers, which might still be bundled by default
-- Likewise, change all "core" DNS solvers into external solvers
-- Provide a minimal "pick and mix" distribution of cert-manager which allows users to specify exactly which issuer types / DNS solvers they want to install
+The cert-manager project roadmap has moved to the [cert-manager/community repo](https://github.com/cert-manager/community/blob/main/ROADMAP.md).
