# About the Help:
#   Add as a comment starting by "help:" the help you need to add to the `bot help` and `bot rules` commands.
#   The command logic needs to be added with ``, and the parameters to supply need to be in capital for example: `echo SOMETHING`

# help:     To run a command on demand:
# help:       `!THE_COMMAND`
# help:       `@NAME_OF_BOT THE_COMMAND`
# help:       `NAME_OF_BOT THE_COMMAND`
