title: Add an Arvados repository

...

Next, we're going to use the Arvados CLI tools on the <strong>shell server</strong> to create a few Arvados objects. These objects set up a hosted clone of the arvados repository on this cluster.

This will be readable by the "All users" group, and therefore by every active user. This makes it possible for users to run the bundled Crunch scripts by specifying @"script_version":"master","repository":"arvados"@ rather than pulling the Arvados source tree into their own repositories.
