 It is not strictly necessary to deploy _both_ SSH and HTTPS access, but we recommend deploying both:
 * SSH is a more appropriate way to authenticate from a user's workstation because it does not require managing tokens on the client side;
 * HTTPS is a more appropriate way to authenticate from a shell VM because it does not depend on SSH agent forwarding (SSH clients' agent forwarding features tend to behave as if the remote machine is fully trusted).
+* HTTPS is also used by Arvados Composer to access git repositories from the browser.
 
 The HTTPS instructions given below will not work if you skip the SSH setup steps.

+h2. Clone Arvados repository
+
+Here we create a repository object which will be used to set up a hosted clone of the arvados repository on this cluster.

+</code></pre></notextile>
+
+Create a link object to make the repository object 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.

+
+In a couple of minutes, your arvados-git-sync cron job will create an empty repository on your git server. Seed it with the real arvados repository. If your git credential helpers were configured correctly when you "set up your shell server":install-shell-server.html, the "git push" command will use your API token instead of prompting you for a username and password.
