problems or questions you have, well repsond as soon as I can.
Please note that all testing is currently on testnet only using the
counterparty XCP asset.
# install the picopayments cli client (sorry no gui wallet just yet)
$ pip3 install picopayments-cli

# Show status of current connections and wallet
$ picopayments-cli --testnet status
# post the wallet address in https://community.storj.io/channel/micropayments-testing and you will be sent some funds for testing

# connect to hub (prints the hex handle of the created channel)
$ picopayments-cli --testnet connect XCP 1000000

# you will have to wait until your deposit is confirmed, then the hub
# will match your deposit so you can recieve funds. After the hub deposit
# is confirmed the micropayment channel is open for use.

# Show status of current connections and wallet
$ picopayments-cli --testnet status

# Show hub status: open connections, liquidity, terms and funding addresses
$ picopayments-cli --testnet hubstatus

# queue payment
$ picopayments-cli --testnet queuepayment SOURCEHANDLE DESTINATIONHANDLE QUANTITY

# do not send more then you have or the other party can receive or it
# will mess up the channel (known issue I have to fix)
