+# 1 Prepare nexus.
+#  -> (a) Make a Nexus user, (b) make a EBICS subscriber
+#     associated to that user
+#
+# 2 Prepare the Ebics bank connection for the nexus user.
+#  -> (a) Upload keys from Nexus to the Bank (INI & HIA),
+#     (b) Download key from the Bank (HPB) to the Nexus,
+#     and (c) Fetch the bank account owned by that subscriber
+#     at the bank.
+
+# 3 Request history from the Nexus to the Bank (C53).
+# 4 Verify that history is empty.
+# 5 Issue a payment from Nexus
+#  -> (a) Prepare & (b) trigger CCT.
