Installation
From Github: git clone the content to ~/.icons folder.

Once downloaded, activate the theme using tweak-tool or from command line: gsettings set org.gnome.desktop.interface icon-theme “shadow”
Icon Themed But Does Not Appear
Most of the time, this is because, the corresponding desktop file has full path in icon name. like, for some app named Foo, the corresponding foo.desktop file (e.g. /usr/share/applications/foo.desktop) may look like:
[Desktop Entry]
Name=Foo
Exec=foo
Icon=/usr/share/icons/hicolor/foo-icon.png
This can not be themed. The workaround is to copy it to your ~/.local/share/applications/ and give the icon generic path like:
[Desktop Entry]
Name=Foo
Exec=foo
Icon=foo-icon
