This is the Z Shell configuration function for new users,
zsh-newuser-install.
You are seeing this message because you have no zsh startup files
(the files .zshenv, .zprofile, .zshrc, .zlogin in the directory
~).  This function can help you with a few settings that should
make your use of the shell easier.

You can:

(q)  Quit and do nothing.  The function will be run again next time.

(0)  Exit, creating the file ~/.zshrc containing just a comment.
     That will prevent this function being run again.

(1)  Continue to the main menu.

(2)  Populate your ~/.zshrc with the configuration recommended
     by the system administrator and exit (you will need to edit
     the file by hand, if so desired).

--- Type one of the keys in parentheses ---

0 と入力する。
→ .zshrcが生成される。

   This is Powerlevel10k configuration wizard. You are seeing it because you haven't
  defined any Powerlevel10k configuration options. It will ask you a few questions and
                                 configure your prompt.

                    Does this look like a diamond (rotated square)?

おわりに

zshを10年ぶりくらいに環境に入れた。
oh-my-zshいまだに好きなのでこれを使うようにしてるけど、他に何か人気なのは出ているのかも今度調べてみようかな。
powerlevel10kは初めて使うので、これから楽しみ。
