how to ignore all file and directory except a directory I need by using .gitignore

Question

When I pushed my project to github I needed a problem.The structure of my project like this:

Now I want to upload .gitignore README.md and all of directory d2 .

I don't want to write directory in .gitignore because the project not only has d1 I don't want to upload.There so many directory(d3,d4,d5) I don't want to upload.

I want to find a way that I can ignore all the directory except d2 .

I have tried to write .gitignore like this:

* !/d2/ !.gitignore !./README.md

But it didn't work.

Do anyone know how to do?Thanks.

You may use the following .gitignore .

/*
!/d2/
!.gitignore
!README.md

* ignores all files in directories in all depth, while /* only ignores the files and directories under the root level.

By the way, if you want that it still works with * , you need to add !/d2/** as follows.

*
!/d2/
!/d2/**
!.gitignore
!README.md
