Hey Mikhail,
Most Wacom tablets, certainly mine, are plug and play. Meaning you just plug in the USB and it’s ready to use.
In the software for the tablet are key (button) settings you can change, mine has 4 buttons on the tablet and 2 on the pen, each of these can be configured to match a keyboard shortcut, like F and Shift+F to adjust the strength and radius of brushes, the pen can match mouse buttons.
This means you can move your keyboard and mouse out of the way so you can use your pen and tablet easier.
The tablet you choose is up to you, more buttons, bigger surface area, with or without a screen, most will do the job, and should come with instructions on how to set your preferences.
A tutorial would probably not be much use as all makes and models will vary to some extent.
