Adding new user, change USERNAME with the name you want to use.
adduser USERNAME
usermod -aG sudo USERNAME
# switch to user
su - USERNAME
Log out and log back in as new user. Be sure to add SSH key to new users ~/.ssh if using SSH to login.
Change directory user and group:
# changes recursively
sudo chown -R username:group directory
# changes only the directory
sudo chown username:group directory
To add zsh and OMZ:

# if the above does not work, run:
sudo apt install coreutils
# load in zshrc changes
source ~/.zshrc
