+### Setup server
+
+This script is installs docker (might be dropped?). It also install postgresql
+with pgpool-ii and configure it. There is also a backup script installed that
+creates dump of the db and seeds it.
+
+> NOTE: The backup script needs to have access to a GPG key to sign the dumps.
+> It also needs a file with the passphrase, see
+> [group_vars/all](group_vars/all).
