+# NOTE FOR TRAEFIK v3 #
+Many guides out there (including, until recently, this repo) reference an older version of the Kubernetes CRDs API group.
+This older version is [deprecated](https://doc.traefik.io/traefik/master/migration/v2-to-v3/#kubernetes-crds-api-group-traefikcontainous) 
+as of Traefik v3 (released [29 April 2024](https://github.com/traefik/traefik/releases/tag/v3.0.0)) and must be updated to the new version
+in your IngressRoute, Middleware, ServersTransport, etc. yaml manifests for Traefik.  Any resources with the deprecated version will not 
+be recognized by Traefik v3.
+
+Old, deprecated version:
+```yaml
+apiVersion: traefik.containo.us/v1alpha1
+```
+
+New, supported version:
+```yaml
+apiVersion: traefik.io/v1alpha1
+```
+This new version is also supported in later releases of Traefik v2, so you can update your Traefik-related manifests 
+to the new version and apply the updated manifests before upgrading your Traefik deployment.
+
+It may be worth reviewing other v2 to v3 migration notes provided by Traefik:
