+# RELEASE PROCESS
+This document describes the process creating a new version of the
+signal specification.
+
+The process, driven by the GENIVI Remote Vehicle Interaction Expert
+Group (RVI EG), is aimed at being lightweight and carried out in public, giving both
+GENIVI members and non-members a say in the creation of a new version.
+
+In git, the ```develop``` branch is used as an integration branch
+accepting pull requests with new and modified vpsec files from
+contributors.
+
+Pull requests are reviewed in the public genivi
+list ```genivi-projects@lists.genivi.org```. Once the review process
+has concluded, the RVI EG decides if the pull request is to be
+accepted or not.
+
+A new signal specification release is created om a quarterly basis at
+the following dates: Jan 1, Apr 1, Jul 1, Oct 1.
+
+If no changes have been agreed upon since the last release of the
+specification, the release is skipped and no new version is created.
+
+A new release is made by merging the develop branch into master, and
+then create a master branch tag named after the release
+date such as ```rel_2016-04-01```.
