Customizing a Puppet in CH and Photoshop Please HELP!!!

i'm trying to customize one of the example puppets in Character Animate, but I keep getting stuck at the photoshop part. I downloaded the puppet, inserted it into a scene, tried all the triggers for the arms, but when it comes time to actually change things on the puppet like skin tone, facial hair, etc, the tutorials all seem to jump and all the sudden they're editing in photoshop, or at least a program that looks like photoshop. I've never used photoshop in my life, so I have no idea how to import the puppet to photoshop to make changes, much less get those changes to import back to Character Animator. Can someone please help??
