Hi, thanks for your contribution! Just one comment, you don't always need sudo to install npm packages globally. This would depend on the OS you're on and the user you're running under.

As such, I prefer to leave it out of the documentation, as users will likely be able to figure this out, and I don't want to encourage everyone to use sudo unnecessarily.

Rest looks good!

Removed. It is a great util tool but i missed the global option hence me creating a TOC for the readme, hopefully might help others see the cli options.

Brilliant, thank you!
