dev-setup VS ohmyzsh

Something like this at least is the most direct answer to your question, as opposed to "you're doing it wrong" which unfortunately seems to be more upvoted. An example of something like this might be https://github.com/donnemartin/dev-setup

If you are not using oh-my-zsh, you are missing out on some amazing plugins. One feature most people wish the terminal had is autocompletion. With the zsh-autosuggestions plugin, your terminal will autocomplete most commands and remember previous ones.

That’s the minimum terminal setup. You can modify the look and add plugins such as autocompletion to your terminal by installing ohmyzsh and using themes such as powerlevel10k. I am already using them.

Somewhat related is "Oh My ZSH!" which is basically zsh on steroids, it's always one of the first things I install on a new computer. It gives things like new colors, themes, plugins, and more. Highly recommend you check it out.

I had just gone through a fun tutorial for setting up oh-my-zsh with a nice color scheme from iterm2colorschemes.com and a decent prompt and I was wondering: can I make my oblique strategy look nice? how can you actually use the colors from your scheme in the output in your cli?

After this you going to visit Oh-My-Zsh which is where the magic will happen.

after automating my dotfiles, I want to automate my installations, after that I want to make my terminal easier to use so I add OMZ with many plugins, after that, I try to automate the backup of my setting on my Gnome but failed, then try using git-lfs for my big files but it turned out to be idiotic moves, bla bla bla many try and fail.
