+# Nexus Core
+
+This is the Nexus Core, a mirror of the Sonatype Nexus Core SVN repository.
+
+## Branches
+
+I used as manual a nice blog entry to create a "one way" mirror of SVN repository:
+
+http://www.fnokd.com/2008/08/20/mirroring-svn-repository-to-github/
+
+So, the setup is similar, we have the following branches:
+
+* vendor - this is 1:1 mirror of the TRUNK of the Nexus SVN, no changes here.
+* master - this is where work is, and *rebase* happens regularly (done manually, not cron-ed like Bob did!)
+
+DO NOT FORK THIS REPO, you will be not able to follow it.
+
+Have fun!
