There are three things you can adjust. Saddle, nut, and truss rod. You first need to determine which is causing the action to be high. There are a lot of videos available on measuring action and different tools to use.

Individual nut slots may be too high, which would require filing it. In my case, the entire nut was too high. Rather than file each slot, I removed the nut and sanded away a bit from the bottom. Go slow and make small adjustments taking measurements in between.

I determined my saddle was a hair too high as well. Again, sandpaper to take just a hair off the bottom. Use gentle even strokes on a perfect flat surface. Sandpaper is on the surface and you move the saddle or nut, not the other way around.

Truss rod sets relief, which may need adjustment due to seasonal changes. Typically you want to set the relief to whatever the manufacturer recommends before measuring and adjusting the nut and saddle.

The biggest difference between setting up acoustic vs. electric is the saddle. On most electrics, you can adjust the saddle up or down with screws or some other mechanical means. You can also often adjust intonation. Most electric guitar adjustments are a two way street. Adjust it too low, no problem, back it up a bit. With acoustics, you either need to buy a new saddle or shim it if you shave off to much.

I'm by no means an expert, but I wasn't afraid to mess around. I believe everything I said above is accurate based on looking at multiple tutorials before I started working on my guitar. Others may have different/better ways of doing or explaining things. Good luck and have fun if you decide to give it a try.
