# Manage Packages Using Spotfire and TERR

Analysts and data scientists can download existing packages, or they can build and test their own packages. They can wrap them in a Spotfire SPK for distribution to analysts in their organization. Spotfire Server administrators can distribute the packages using Spotfire Server, and Spotfire web client users can view Spotfire analyses that use the packages.

Note: Because this documentation specifically addresses using TERR in Spotfire Analyst, the instructions demonstrate using the TERR tools available from the Spotfire Analyst user interface. Experienced R or TERR programmers, or programmers using TERR from the stand-alone console can perform many of these tasks directly from the console or from within RStudio. See the TERR Technical Guide and Language Reference for more information.

For the following tasks, Spotfire products each play a role in building, distributing, using, and maintaining packages in the Spotfire predictive analytics platform.
