Register the Admin User
Connect to the local SPARKL node
sparkl connect http://localhost:8000
Register and sign in the default administrator user
sparkl login --register admin@localhost
This particular user is pre-defined as administrator.
--registerflag is required on first sign-in only, and prompts you to define the administrator password.
Show the configuration tree for admin@localhost now we're logged in
This shows you a single folder, present by default, called Scratch.
Now you can try the Hello World example to be sure your installation is working fine.
