Add .gitignore

[mirdaki]

You have some files (well just .DS_Store right now) that don't add anything to the project and shouldn't be tracked in Git. You can add a .gitignore file to prevent those from being added in the future (though the ones already tracked will need to be manually deleted). I like to use gitignore.io to generate the file content, because I can quickly add different types of files to be ignored (such as MacOS and Python ones).

I will add the .DS_store to the .gitignore. I always forget that file.
There is a .gitignore but I added the '.gitignore' to itself so that it wouldn't be tracked. I don't know if thats standrd or not

It is not. You'll want to track the .gitignore so other people on your project will automatically block files too. I'll usually add the standard Windows and Linux files to my .gitignore as well, so no contributors would add the standard OS stuff either.
