This chapter describes how Taverna can be configured in a multi-user setting. It details the bootstrap process used by Taverna when first invoked by a user and how to override aspects of this process to insert your own configuration, software repositories, profiles, plugin sets etc. If you are a system administrator installing Taverna in a central location for use by multiple individual users you should read this, if you are just using Taverna on a single machine with the default supplied profiles, update manager settings etc this chapter is not required.
