Description of the problem:

In our Assisted Installer documentation, there is a section titled "Adding hosts with the web console" [1]. However, this section lacks critical information regarding the need to create a Bare Metal Host (BMH) and a machine object, which is explained in another section [2].

Additionally, in section [2], it should be clarified that creating the BMH and machine object is optional, depending on the platform of the cluster.
