The CLIcompanion has three columns. The first column is the command. The second column shows you if the command needs information from the user. Some commands need a path to a file. Others might need a package name. The third column is the command description.
The add command feature allows for three pieces of information to be stored for each command. Be mindful that not all commands will need the user variable field.
