" Your test account is all set! Save your keys to make other API calls on the network. "

@kame.japan2 it sounds like you created an account on the Stellar test network. Congrats! You can now try out other API commands in the
Stellar Laboratory. For instance, you can send lumens, issue your own asset, and build a multi-signature transaction.
