+The `event` command contains subcommands to trigger mock events for local webhook testing or migration.
 
 All commands exit the program with a non-zero exit code when the command fails, including when an event does not exist, or when the mock EventSub WebSocket server does not start correctly.

+## Configure
+
+Used to configure the forwarding address and/or the secret used with the `trigger`, `verify-subscription`, and `retrigger` subcommands.
