binkd Docs are available at http://www.doe.carleton.ca/~nsoveiko/fido/binkd/man/binkd.man.html
Ok, let's just run through them then... I'll use the following:

bP
  for your binkd path (Mine is /usr/bbs/sbbs/fido)
sP
  for the sbbs path
fZ
  for the Fidonet Zone (1 for north america)
fA
  Your complete fidonet address (ie: 1:140/17)
SysN
  For your BBS name (ie FreeBSD Synchronet)
SL
  For your BBS location (ie Yorkton, Sk)
SN
  For the sysop name (ie Stephen Hurd)
HfA
  Your hubs address (ie 1:140/1)
HiA
  Your hubs internet address
PASS
  The password for the hub

Note, IONs are listed as 300bps in the nodeinfo.

    prescan
    node HfA@fidonet -md HiA PASS

-------- End of binkd.conf --------
Then you need to set up sbbsecho.
Here's my sbbsecgo.cfg file with the same replacements as above:
-------- Start of sbbsecho.cfg --------

    NOTIFY 1
    SECURE_ECHOMAIL
    FUZZY_ZONE
    FLO_MAILER
    KILL_EMPTY
    LOG 0FFFFFFF
    INBOUND bP/inbound/
    SECURE_INBOUND bP/inbsecure/
    OUTBOUND bP/outbound/
    ARCSIZE 0
    PKTSIZE 0
    PKTPWD ALL PASS
    PACKER ZIP 0 504B
      PACK /usr/local/bin/zip %f %s
      UNPACK /usr/local/bin/unzip -j %f -d %s
    END
    USEPACKER  ZIP ALL
    AREAFIX    ALL PASS
    ROUTE_TO   HfA ALL

-------- End of sbbsecho.cfg --------
That's all find and dandy if Fido is the only FTN network you're on... but what if you're a member of more than one.. For example, xleague (http://www.x-bit.org) *and* FidoNet? Well, things get a teensy bit more complicated. We'll need a couple more replacements.

xA
  Your complete x-league address (ie: 777:777/52)
HxA
  Your x-league hubs address (ie: 777:777/0)
HxiA
  Your x-league hubs internet address (ie: x-bit.org)
xPASS
  The password for the x-league hub

Moreover, we'll have to explicity route all FidoNet stuff by zone to your fidonet hub. The DEFAULT ZONE does not change per network with sbbsecho... it is what's set up as the zone for your first FTN address. I've bolded all the lines that are different from the previous example.
-------- Start of binkd.conf --------

    domain fidonet bP/outbound fZ
    domain fido alias-for fidonet
