Basic Usage Question

[mlstudent2]

I apologize if I overlooked it and if this isn't an "issue", but I couldn't find any basic steps/commands needed to reproduce the change in expression found in the teaser image: https://raw.githubusercontent.com/Puzer/stylegan-encoder/master/teaser.png

I was able to encode an image successfully using the commands in the readme but I can't seem to find any documentation on modifying the expression or angle of a face after doing so. All I'm trying to do is tinker with adjustments on a custom image, am I misunderstanding the functionality of this repo?
