Adding a new component

[gioacchinomauri]

I'm using GetSimple 3.0.

In "theme"-> "edit components" there is the possibility to add a new component. When i click "add component" a new box appears at the bottom of the page in which i can insert title and text.

I'm using the default installation of GetSimple without plugins and i want another "sidebar" component below the original one. How can i add this new component in the page ?

I have no experience in php

Thanks,
