how to create a user account which reset after restart

[milton]

Hi,

Orca master in Ubuntu 20.04, I create a user account and made some 
settings for some one new with Ubuntu to try it out. After the person 
use the account and restart I would like the account be restored in the 
original state. 10 years ago I heard it had to do with /etc/skel/ I 
found that until Ubuntu 12.04 the command ofris-en did the job. Your 
help/advice is very appreciated.
