This is the script I use to set up my customised zsh setup on Debian. (You can always edit the file to use your preferred package manager, but for the time being, mine uses apt by default.).
Simply download the repository. It doesn't matter if you use git clone or the github interface; all we need are the shell files.
git clone https://github.com/mayank-pq2q4/zsh-setup-script.git <~/your-preferred-directory>
Log in as the user for whom you want the zsh to be activated.
Type (replace default shell with your current shell, usually bash but run ps -p $$ just to be sure)
<default-shell> myZSH.sh
You will now enter the zsh shell. After that, we install the necessary plugins and themes, which can be customised to your liking.
zsh myZSHPlugins.sh
Following that, you'll be looking at the .zshrc file. Simply include the plugins that you desire.

Simple route if Vi isnt installed:
Simply open the /.zshrc file in your preferred text editor.
No, I don't have another editor besides vi.
Try nano, which is available on many distributions, or do the following if nano is not available.:
If you don't know how to navigate a vi editor, simply press esc to return it to NORMAL mode (just in case you accidentally went into another mode), then i to take it to the editable mode INSERT, then use arrow keys to navigate to the desired place and edit them. If you believe you made a mistake, simply press esc then u to undo your changes. then i to edit again When you're finished, press esc and then shift + z + z or ZZ. This will save your file.
To learn more about Vi, type man vi or search online; however, I do not recommend this editor for complex tasks. For that, use vim/nvim or emacs.

Log out of the system (in wsl, simply close the session and relaunch it), then log back in and launch a terminal. By default, I selected powerlevel10k as my zsh theme, and if you don't change that setting, you'll be greeted by a configuration wizard. Choose your best look, and that's all there is to it!
