Special instructions for downloading via command line courtesy of @jlagarespo :
git clone https://github.com/sgossner/VSCO-2-CE.git
If you are using windows, just install the git from the official installer and the architecture your system is using. If you are using any linux distro GNOME based just do sudo apt install git (you may need some privielegies to do this.) If you are though, using any xfce distro just install it with pacman. And if you are using mac, or any BSD based system, just install homebrew.
If you are still having trouble with the download, even after trying different browsers and networks (if available), then use the mirror below:
