# Enabling the DS

In order to enable the DS to modify a theme, edit a quiz with the theme you want to modify, go to General Settings, and click on the *Advanced* tab:

![](/files/WQHnZxlOG0F5Kto3VR5z)

Enable the DS by clicking on *Use Design System*:

![](/files/uyPnASBA47soWOYHFIYd)

{% hint style="info" %}
Once the DS is enabled, you will work on a forked branch of the theme so any updates including fixes to the main branch will not be applied to your branch.
{% endhint %}

When the DS is enabled, a new tab with the DS builder will show up:

![](/files/Ub6af3NoWKvNVmwS4XXv)
