Change dashboard theme

Is it possible to customise the dashboard theme on erpnext. Where should I start. I found no documentation on this … sorry I am a newbie

Iwould like to change the icons too. I want to use custom images for the icons. Can I also rename the base apps to some other name…for example crm to scrm

You can change the desktop icons by typing ‘icon’ in the awesome bar, and clicking on the first result.
You can change the desktop background by going to your user settings.
You cannot change app names. You will break the system if you try.
