Use the describe command to display more information about an individual add-on (for example, available versions, name, description, license).

addon describe addonId[:addonVersion] [--no-cache] [--offline] [--catalog=$URL] [--batch-mode]

To view information about a specific version of the add-on, simply add the addonVersion right to the addonId. The usage of the options listed in the above syntax is in the same way as the list command.
