How to do Linearity Correction for X, Y, Z axis?
I read the instructions for calibrating Linearity Correction on the E axis, and that wasn't very hard. Is there anything similar for the other axes? I noticed there are menu options for them.
Also, what types of printing artefacts will that fix?
Also, where can I find information about what linearity correction even is?

Good questions, I'd like to know the answers to those as well.
If there are features available in menus that can improve the quality of prints even more then should be some explanation of how to use them.
There is also this thread from a few months ago but still no official answers on how to find out what it is best to set those to:

I tried taking the gcode for the e axis tower test from https://help.prusa3d.com/l/en/article/p2xdpg0ul8-extruder-linearity-correction-calibration and did a find replace to swap the E axis for the X axis. The gcode does a TMC_SET_STEP on every layer with increasing numbers though, and I don't understand why. It does, however, completely mess the print up when done on the X axis.

The XYZ linearity corrections appeared in the firmware just after the extruder linearity did. AFAIK no explanation of them or guidance as to their use has ever been published.

Well, in the firmware they are handled the same as the E axis, just for different motors, so they should at least be similar?
