Hello @rustam-mukhametshin, thanks for the feedback.

ionicons is its own separate project from Ionic Framework. It does not include its own component wrapper for Angular, as it does when using it from Ionic Framework. The distribution strategy for ionicons currently is to have it act as a ghost dependency in Ionic Framework, so that developers do not have to have ionicons as a project dependency for the component to work in their projects and to work around limitations of using different Stencil projects within the same context. The only thing that installing ionicons independently in an Ionic Framework project does, is that you can reference new icons/SVGs that are available in the later releases from the one distributed with Ionic Framework.

The documentation for using ionicons by itself should not include information about the @ionic/angular package, as they can be used independently (a project can use ionicons without Ionic Framework).
