### Manual Installation

To build the theme the following packages are required
* `autoconf`
* `automake`
* `sassc`
* `pkg-config` or `pkgconfig` for Fedora
* `git` to clone the source directory
* `optipng`
* `inkscape`

The following packages are optionally required
* `parallel` for speeding up build by rendering assets in parallel
* `gnome-shell`for auto-detecting the GNOME Shell version
* `libgtk-3-dev` for Debian based distros or `gtk3-devel` for RPM based distros, for auto-detecting the GTK3 version

**Note:** For distributions which don't ship separate development packages, just the GTK 3 package is needed instead of the `-dev` packages.

For the theme to function properly, install the following
* GNOME Shell 3.18 - 3.30, GTK 3.18 - 3.24
* The `gnome-themes-extra` package
* The murrine engine. This has different names depending on the distro.
  * `gtk-engine-murrine` (Arch Linux)
  * `gtk2-engines-murrine` (Debian, Ubuntu, elementary OS)
  * `gtk-murrine-engine` (Fedora)
  * `gtk2-engine-murrine` (openSUSE)
  * `gtk-engines-murrine` (Gentoo)
