+## Main
+This is my "private" overlay. There will be different ebuilds from different sources,
+mostly temporary before submitting to the main gentoo bugtracker at http://bugs.gentoo.org.
+
+## Setup & synchronisation
+
+Just run layman from app-portage/layman with needed privileges, e.g. root:
+
+```sh
+$ layman -f -o https://git.holgersson.xyz/holgersson-overlay/plain/repository.xml -a holgersson-overlay
+```
+
+and optional for global updates:
+
+```sh
+$ layman -S
+$ emerge --sync
+```
+
+You might set USE="sync-plugin-portage" for layman, too.
+
+
+## Maintainer
+If you encounter Bugs, send a mail to
+
+   nils [dot] freydank [ascii-symbol-no64] posteo [dot] de
+
+Bug descriptions, suggestions, patches, critics and chorus of praise
