Confirm the command on the readme file

[IvanFan]

Hi

I just read through the readme doc and try to make it work.
I executed the command in the doc:
python --config config/moving-gif.yaml --driving_video sup-mat/driving_video.gif --source_image sup-mat/source_image.gif --checkpoint path/to/checkpoint

But it doesn't work.
It's missing the python file and I cannot find the driving_video.gif and source_image.gif in sup-mat.
I noticed that the network accept stacked '.png' and there are two png images under sup-mat.
Just want to confirm the correct command of running the check point. Should it be :

python demo.py --config config/moving-gif.yaml --driving_video driving.png --source_image source.png --checkpoint moving-gif-ckp.pth.tar

If it's correct, I'm happy to rise a PR to fix it :)
