Should I use git add before or git commit before?

You should first execute git add . To stage the new/modified files and then git commit -m "your message" to write those changes to the repository.

You need to add before you commit. Otherwise there is nothing new to commit.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
