No Documentation to install onto core

[1Map]

I do not use collections, just a core, but having trouble understanding how to deploy the DIH to just my core. You just talk about collections as in:

Create a products collection
curl "http://localhost:8983/solr/admin/collections?action=CREATE&name=products&numShards=1"

Deploy package on the collection
bin/solr package deploy data-import-handler -y -collections products
