+.. _credentials section: https://github.com/gnzsnz/ib-gateway-docker?tab=readme-ov-file#credentials
+
+
+Connecting to the API from `piker`
+---------------------------------
+In order to expose the container's API endpoint to the
+`brokerd/datad/ib` actor, we need to add a section to the user's
+`brokers.toml` config (note the below is similar to the repo-shipped
+template file),
+
+.. code:: toml
+
+    [ib]
+    # define the (set of) host-port socketaddrs that
+    # brokerd.ib will scan to connect to an API endpoint
+    # (ib-gw or ib-tws listening instances)

+    # of user-defined-account "names" (as defined below) here
+    # determines which py-client connection is given priority to be
+    # used for data-feed-requests by according to whichever client
+    # connected to an API endpoing which reported the equivalent
+    # account number for that name.
+    prefer_data_account = [
+        'paper',
+        'margin',
+        'ira',
+    ]
+
+    # define "aliases" (names) for each account number
+    # such that the names can be reffed and logged throughout
+    # `piker.accounting` subsys and more easily
+    # referred to  by the user.
+    #
+    # These keys will be the set exposed through the order-mode
+    # account-selection UI so that numbers are never shown.
+    [ib.accounts]
+    paper = 'XX0000000'
+    margin = 'X0000000'
+    ira = 'X0000000'
+
+
+the broker daemon can also connect to the container's VNC server for
+added functionalies including,
+
+- viewing the API endpoint program's GUI for manual interventions,
+- workarounds for historical data throttling using hotkey hacks,
+
+Add a further section to `brokers.toml` which maps each API-ep's
+port to a table of VNC server connection info like,
+
+.. code:: toml
+
+    [ib.vnc_addrs]
+    4002 = {host = 'localhost', port = 5900, pw = 'doggy'}
+
+The `pw = 'doggy'` here ^ should the same value as the particular
+container instances `.env` file setting (when it was run),
+
+.. code:: ini
+
+    VNC_SERVER_PASSWORD='doggy'
+
+
+IF you also want to run ``TWS``
+-------------------------------
+You can also run it containerized,
+
+https://github.com/gnzsnz/ib-gateway-docker?tab=readme-ov-file#using-tws
+
+
+SECURITY stuff (advanced, only if you're paranoid)
+--------------------------------------------------
+First and foremost if doing a "distributed" container setup where you
+run the ``ib-gw`` docker container and your connecting API client
+(likely ``ib_async`` from python) on **different hosts** be sure to
+read the `security considerations`_ section!
+
+And for a further (somewhat paranoid) perspective from
+a long-time-ago serious devops eng..
+
+Though "``ib``" claims they filter remote host connections outside
+``localhost`` (aka ``127.0.0.1`` on ipv4) it's prolly justified if
+you'd like to filter the socket at the *OS level* using a stateless
+firewall rule::
 
     ip rule add not unicast iif lo to 0.0.0.0/0 dport 4002
