+# Alpha-Quadrant
+
+Gentoo Overlay - experimental ebuilds of misc packages which are not present in
+the official portage tree.
+
+## Vision
+This overlay should help bring a wider range of services to my servers.
+The selection is subjective and is due to my current moods and interests.
+
+## Installation
+
+Just add following file to `/etc/portage/repos.conf` and call it e.g.
+`alpha-quadrant.conf`: 
+
+```
+[AlphaQuadrant]
+priority = 20
+location = /var/portage/alpha-quadrant
+sync-type = git
+sync-uri = https://git.migmedia.net/gentoo/alpha-quadrant.git
+auto-sync = true
+```
