Installing from base (dinit).
Following the wiki installation page, a non root user will be added to the system.
No information is given about the system configuration needed to add an user to the sudoers file.
For users that are not very skilled in cli this could be a problem, so i suggest to add the info required to configure the editor of choice in visudo, to enable the wheel group in visudo and to add the user(s) in the wheel group.
