 Similarly, the introduction of a new plugin version might only lead to a new minor version release of KubeBuilder, since no breaking change is being made to the CLI itself. It'd only be a breaking change to KubeBuilder if we remove support for an older plugin version. See the plugins design doc [versioning section][cli-plugins-versioning]
 for more details on plugin versioning.

 ## Introducing changes to plugins
 
 Changes made to plugins only require a plugin version increase if and only if a change is made to a plugin
 that breaks projects scaffolded with the previous plugin version. Once a plugin version `vX` is stabilized (it doesn't
 have an "alpha" or "beta" suffix), a new plugin package should be created containing a new plugin with version
-`v(X+1)-alpha`. Typically this is done by (semantically) `cp -r pkg/plugin/vX pkg/plugin/v(X+1)` then updating
+`v(X+1)-alpha`. Typically this is done by (semantically) `cp -r pkg/plugins/golang/vX pkg/plugins/golang/v(X+1)` then updating
 version numbers and paths. All further breaking changes to the plugin should be made in this package; the `vX`
 plugin would then be frozen to breaking changes.
 
+You must also add a migration guide to the [migrations](https://book.kubebuilder.io/migrations.html)
+section of the KubeBuilder book in your PR. It should detail the steps required
+for users to upgrade their projects from `vX` to `v(X+1)-alpha`.
+
 ### Example
 
-KubeBuilder scaffolds projects with plugin `go.kubebuilder.io/v2` by default. A `v3-alpha` version
-was created after `v2` stabilized.
+KubeBuilder scaffolds projects with plugin `go.kubebuilder.io/v3` by default.
 
 You create a feature that adds a new marker to the file `main.go` scaffolded by `init`
 that `create api` will use to update that file. The changes introduced in your feature
 would cause errors if used with projects built with plugins `go.kubebuilder.io/v2`
 without users manually updating their projects. Thus, your changes introduce a breaking change
 to plugin `go.kubebuilder.io`, and can only be merged into plugin version `v3-alpha`.
