+## Gentoo (native)
+
+Snapcast is available under Gentoo's [Portage](https://wiki.gentoo.org/wiki/Portage) package management system.  Portage utilises `USE` flags to determine what components are built on compilation.  The availabe options are...
+
+    equery u snapcast
+    [ Legend : U - final flag setting for installation]
+    [        : I - package is installed with flag     ]
+    [ Colors : set, unset                             ]
+     * Found these USE flags for media-sound/snapcast-9999:
+     U I
+     + - avahi       : Build with avahi support
+     + + client      : Build and install Snapcast client component
+     + - flac        : Build with FLAC compression support
+     + + server      : Build and install Snapcast server component
+     - - static-libs : Build static libs
+     - - tremor      : Build with TREMOR version of vorbis
+     + - vorbis      : Build with libvorbis support
+
+
+These can be set either in the [global configuration](https://wiki.gentoo.org/wiki//etc/portage/make.conf#USE) file `/etc/portage/make.conf` or on a per-package basis (as root):
+
+    if [ ! -d "$DIRECTORY" ]; then
+      mkdir /etc/portage/package.use/media-sound
+    fi
+    echo 'media-sound/snapcast client server flac
+
+If for example you only wish to build the server and *not* the client then preceed the server `USE` flag with `-` i.e.
+
+    echo 'media-sound/snapcast client -server
+
+Once `USE` flags are configured emerge snapcast as root:
+
+    $ emerge -av snapcast
+
+
+Starting the client or server depends on whether you are using `systemd` or `openrc`.  To start using `openrc`:
+
+    /etc/init.d/snapclient start
+    /etc/init.d/snapserver start
+
+To enable the serve and client to start under the default run-level:
+
+    rc-update add snapserver default
+    rc-update add snapclient default
