If you're heading to Sideburn, get the dust app. (If you haven't already). https://dust.events/docs/intro/ (link for Android or iOS app is here).
It is an app (for burning man & regional events) that has details of theme camps, art, music & the events on during the festival. They may have a paper guide and the app can be more up to date.
I recommend having a look through the events so you have the option of preparing for any you require something specific for (like a particular color clothing etc). The app doesn't require internet access after retrieving the event data if you don't have reception at the location.
I have friends who ask "why can't you just text like a normal human" when I call.
