All you need to do to install this theme in its base configuration is running install.sh as root (or any other user that has access to /usr/share/themes) and the theme is ready to use.
This theme aims to be easy to configure and change. If you want to edit the gtk3 theme, you only have to edit the gtk.css.
For the gtk2 theme you'll have to edit the gtkrc file. Both gtk2 and gtk3 have an assets.svg file for the images.
There are only a few colors which have been used in the creation of this theme, these are:
#181818as primary background color#282828as secondary background color#aaaaaaas primary foreground color#616161as secondary foreground color#752a2aas highlight color
Once you change the assets.svg file you'll have to regenerate the assets using the render-assets.sh script.
This requires inkscape and optionally optipng for compressing the output images.
If you want to change the name of the theme, all you have to do is edit the index.theme file and replace every occurance of Arc-Undead with the new name.
After changing anything, you'll have to reinstall the theme using the install.sh script.
