Oh My Zsh is an alternative to the default shell

I'm being picky, perhaps, but Oh My Zsh isn't a shell, zsh is... and zsh has been the default shell on Macs for a while because Apple doesn't want to use copyleft software.

I bring this up because there are a ton of articles which say the same thing, and it's misleading for new users, who are already going to be confused between the terminal, the shell, the command prompt, etc.

[Maxime HEBRARD]

Point taken. I edited the sentence for

"Oh My Zsh is a framework to manage the configuration of the shell and come with a collection of themes."

Hope that rectify the message.

Thanks for the feedback. Always open to suggestion for improvement
