How to .gitignore all files/folder in a folder, but not the folder itself?

https://stackoverflow.com/questions/4250063/how-to-gitignore-all-files-folder-in-a-folder-but-not-the-folder-itself/5581995#5581995

put this .gitignore into the folder, then git add .gitignore

*
*/
!.gitignore

The * line tells git to ignore all files in the folder, but !.gitignore tells git to still include the .gitignore file. This way, your local repository and any other clones of the repository all get both the empty folder and the .gitignore it needs.

Edit: May be obvious but also add */ to the git ignore to also ignore sub folders.
