Question about Dietpi Desktop

I need a graphical interface for DietPi since I use a bot that requires a browser, and of course… I didn’t know this. If I install it, do I lose everything I currently have?

What do you mean by loosing everything? Installation of a software, like desktop, will not remove other software. Maybe you can be more specific on your request.

I mean losing everything I have installed so far on my Raspberry. I understand that everything is maintained, right?

As said, nothing will be removed just installing another software.

In such cases, I install xfce using dietpi-software.
