# Everything following the "#" character is ignored along with blank lines. Values can be set for various
# parameters in a simple and understandable format with the following syntax:
# KEY := "VALUE"
# Every time you change this configuration notecard, the script will reset itself and the new configuration
# will be read from this notecard.
 
# The "corrade", "group" and "password" settings must correspond to your settings in Corrade.ini
 
# This is the UUID of the Corrade bot.

# The password for the group.
password = "mypassword"
 
# The avatar to whom local chat will be relayed to.
