 ### Convert declarations to standalone
 In this mode, the migration will find all of the components, directives and pipes, and convert them
-to standalone by setting `standalone: true` and adding any dependencies to the `imports` array.

 **Note:** NgModules which bootstrap a component are explicitly ignored in this step, because they
 are likely to be root modules and they would have to be bootstrapped using `bootstrapApplication`
