An update from 30 June has this information:
"We will be asking EU citizens to make an application to the Home Office for a residence document demonstrating your new settled status. We will make the process as streamlined and user-friendly as possible for all individuals, including those who already hold a permanent residence document under current free movement rules. We expect the new online application system to be up and running in 2018.
Your residence document will prove (for example, to employers or public service providers) that you have permission to continue living and working legally in the UK."
