-A _managed resource_ is anything Crossplane creates and manages outside of the
-Kubernetes cluster.
-
-This guide creates an AWS S3 bucket with Crossplane.
-
-The S3 bucket is a _managed resource_.
-
-Crossplane v2 allows you to compose namespaced resources. To better support this
-new ability, managed resources (MRs) are now namespaced in Providers that have
-been updated for Crossplane v2.
-
-To support backwards compatibility while users are adopting Crossplane v2, each
-provider will offer the legacy cluster scoped MRs in addition to the new
-namespaced MRs.
-
-For example, when the AWS provider that has been upated to support Crossplane v2
-is installed during this guide, you will see two CRDs for each type of managed
-resource:
-
-1. A legacy cluster scoped MR in the `*.aws.upbound.io` API group
-1. A namespaced MR in the `*.aws.m.upbound.io` API group
