Assets are primarily images used for rendering visual environments.
VSRL downloads assets from the public GitHub repository into ~/.vsrl.
If you would like to modify your local assets, you can do so by first running
an environment and then editing files in your ~/.vsrl directory.
Project maintainers can update the assets by running:
zip -r assets.zip *;
git commit -m "Updated assets." assets.zip;
git push
in this directory.
