-You can have multiple blocks with different time periods (`hour` setting) or starting points (`start_period` setting) as needed. It will work with whole hour or half hour blocks in the `hour` setting.
+`region` is the region letter (e.g. `H`) from the end of your tariff code which will look something like `E-1R-AGILE-18-02-21-H`.  The tariff code used to be found on the [Octopus Energy developer dashboard](https://octopus.energy/dashboard/developer/) webpage in the Unit Rates section for your account, but Octopus seem to have removed this.
+
+The easiest way now to get the tarrif code (and region) for your import and export account is using the [Octopus Energy Integration](https://github.com/BottlecapDave/HomeAssistant-OctopusEnergy/):
+
+Install, configure and start the integration, go to Developer Tools/States and filter on `current_day_rates`, then look at the attributes of the _current_day_rates and _export_current_day_rates entities for the tarrif_code attribute which will be formatted something like `E-1R-AGILE-FLEX-22-11-25-H`.
+
+`import_code` and `export_code` should be specified from the tariff code retrieved above with the preceeding `E-1R-` and the trailing `-H` removed.  If not specified they default to `AGILE-FLEX-22-11-25` and `AGILE-OUTGOING-19-05-13` respectively.
+
+NB: If you get the tariff code wrong (e.g. forget to remove the E-1R- prefix or -H suffix) you will get an error `ERROR octoblock: Error 404 getting incoming tariff data: {"detail":"Not found."}` reported in the appdaemon log and the rest of the octoblock configuration (custom blocks etc) will be ignored!
