 ### General Settings
-The following settings determine how the bot responds. By default, the bot will not spam the default channel. Setting `respond_by_dm_only` to `True` will force all messages to be sent via DM, which may not be desired. Setting it to [`False`] will allow responses in the channel for all to see.
