[Koha] Question about values for create_surperlibrian.pl

For a new installation, does the following make sense? create_superlibrarian.pl --userid ________ --password ________ --branchcode main --categorycode main --cardnumber 1 If some or all of the --branchcode, --categorycode, or --cardnumber values are not what a beginner wants, what should I be supplying? (Or how can I found out what I should be supplying?) -- Christos Hayward
