#     # A human-readable short name. This is used to label IRC status rooms
#     # where matrix users control their connections.
#     # E.g. 'ExampleNet IRC Bridge status'.
#     # It is also used in the Third Party Lookup API as the instance `desc`

#       # If the user with the same IRC nick as the one who sent the quit rejoins a channel

#     botConfig:

#       # which maps from IRC -> Matrix. You can disable the bot entirely which

#       # in the room. If there are no users in the room (or if there are users
#       # but their connections are not on IRC) then nothing will be bridged to
#       # Matrix. If you're concerned about the bot being treated as a "logger"
#       # entity, then you may want to disable the bot. If you want IRC->Matrix
#       # but don't want to have TCP connections to IRC unless a Matrix user speaks
#       # (because your client connection limit is low), then you may want to keep
#       # the bot enabled. Default: true.

# The original registration.yaml file generated by AppService IRC is merged with this config override,
# to produce the final registration.yaml file ultimately used by both the bridge and the homeserver.

# We do this to ensure consistency:
# - always having an up-to-date registration.yaml file (synced with the configuration file)
# - always having the same AS/HS token and appservice id in the registration.yaml file
