+#+TITLE: Project Releasing Process Documentation
+
+* Brief description
+
+  The document describes the releasing process for the components we use
+  in adaptation build process besides the adaptation packages themselves.
+  A good summary would be project updates.
+
+  The components are the are:
+  + Documentation for Releasing, Testing, and building
+  + Build scripts
+  + Releasing and other maintenance scripts
+
+  The goal of this is to track issues that not adaptation specific but come
+  from issues in the documentation or other processes around the adaptations.
+
+  Sometimes these issues are first device specific but usually the affect all ports
+  in the long run.
+
+* Release process

+
+  Branch of a release using ~osc_release_branch~, the release should be branched of from the
+  non-versioned repository to a new release that is named after the time you update.
+  E.g. ~date +%d-%m-%Y~.
+
+  The release is only used for tracking project updates, devices always use the non
+  versioned configuration.

+  Thu save space.
