Your shard site is succesfully installed!
Your main pages (news, timeline, posts, network, about) are still pretty empty. Only the timeline page contains 4 dummy posts, of which this is one, which you should delete later.

You should start by going to your dashboard and look around. You should check out the settings, set your profile, and most important, create two new users, one with role 'editor' and one with role 'administrator', and delete the existing default administrator user 'shard'.

(Don't forget to delete this dummy post later)
