It would be better if we allow users to specify what to include or exclude by using the content of .gitignore. Additionally, we should consider adding the .git directory, since it is not ignored by .gitignore.

I was thinking of it but it will be tricky to implement if you need to support all .gitignore hacks, I will try to implement an initial version of it

Thank @EmadAnwer, for your suggestions on using .gitignore in the script.
I have made some updates to your code and hope they are helpful for everyone.

Cheers 🍻
