#example:
#   ./scripts/register.sh --coldkey <YOUR COLDKEY> --password "<password with special chars escaped>" --hotkeys <YOUR HOTKEY1> <YOUR HOTKEY2>
# NOTE if you pass in the password here, you'll want to put a space in front of the command (like above) so that it won't save to history
# RISK ^^^ look at the NOTE above

#########################
# WHAT THIS SCRIPT DOES #
# USE AT YOUR OWN RISK  #
#########################
# You need a wallet for a coldkey, that's YOUR COLDKEY
# You need some amount of Tao in that wallet, enough to register to the subnet you want to register to
# THEN
# Pass in the hotkey(s) you want to register (they don't have to exist - we'll create them for you) [See example above]
# Let the script do the rest
# -- sends "y" keys when needed to confirm registration
# -- sends your password when needed to decrypt the wallet/send tao
# -- keeps trying until you stop it (even if it's successfully registered)
# RISK: this script is unsupervised and WILL spend your Tao, please review and determine for yourself if this is a RISK you are willing to take
