### System

When you log in to eliona with your access data, you log in to the system.

### Projects

Within a system, there is one or more projects.&#x20;

## Who can create projects?

Projects can be created by users who have a [-> system role](https://docs.buildings.ability.abb/collection/english-v14/roles#systemrollen) assigned that has write permissions for "Projects"

For each project, users can be granted their own permissions. The users of all projects are visible in the system settings.

## How should projects be structured?

Eliona can be customized down to the smallest detail to your individual requirements. This also applies to the project structure. There are no rules regarding the scope of a project.&#x20;

For example: You have several infrastructures distributed worldwide. \
You could now create a separate project for each infrastructure.&#x20;

You could also create projects by geographic region, and create separate projects for Europe, Asia, etc., and sort all corresponding infrastructures into the respective projects. &#x20;

But you could also create a single project and sort all your infrastructures into it.&#x20;

None of these solutions is right or wrong.&#x20;
