I suggest reading the information guide that came with your tablet. I have a few Wacom models, and the driver installation comes with a little config program that lets you configure all the buttons on the pen/tablet depending on what app you are in, this is super duper handy for pretty much every program. I have it set up so that in Photoshop one of my pen buttons is undo, another could be whatever tool I’m using most often, etc.
Hopefully your tablet came with some software such as Painter. Painter is so fun to use with a tablet, they have tons of different brush strokes etc. Of course you can do most of this in Photoshop too, but if you’ve been given the software, take a look at it!
What other programs do you have in terms of graphic/photo editing?
Personally I didn’t feel the tablet was hard enough to warrant using tutorials, but if I were having problems in a certain program I would google ”[program name] tablet configure” and would usually get some help.
If you have any other questions feel free to ask :)
