# Why are roles so important?

Since the introduction of ACL, it is particularly important to assign newly created users to a project immediately. A user without an assigned project cannot see anything in eliona and cannot perform any actions.

{% endhint %}

### Why is that?

If a user is not assigned to any project, then for this user *Users* no project role applies either. 

If no project role applies to a user, only the settings of the system role apply. 

The default system role of every new user is "System-User". This role has no read permissions at all. 

Therefore, a user with the system role "System-User" cannot see any menu items and cannot perform any actions.
