I have data directory in project's root. It has images directory and some files. Here is example:

```
data
├── images
│   ├── image1.jpg
│   ├── image2.jpg
│   └── image3.jpg 
├── results.csv
└── r.txt

```

What to write in gitignore, to ignore files from data/ directory (that is results.csv and r.txt) and files from images/ directory (image.jpg, image2.jpg, image3.jpg)?

When I commit it, folder structure in repository should be:

```
data/
└── images/

```

So, I just want empty folder structure to be commited.
