It's a nested hierarchy.

Think of it as xml:

<modXSettings>
    <foo>
        <name>Peter</name>
        <other>other</other>
    </foo>
    <perms>god</perms>
</modXSettings>

It is the most efficient way to store a set of data, i.e. in one variable
that has some defined structure.

You reference it with:

$modXSettings['foo']['name']
etc

best,
