Here is a link to Carthage
:
https://github.com/Carthage/Carthage
It additionally adds some changes in project files so I can simply remove extra files/folders and it will work but I can't use Carthage
in future again because of some errors.
And of course there is no concrete instruction how to do it on its official page.
Removing Carthage has actually been pretty easy for me.

run script put in place to keep your Carthage frameworks up to date. Simply click the x in the top right
You should always be able to add Carthage back if you want, but these steps should remove it from a particular Xcode project, while keeping the frameworks you want.
