# Getting Package Help

Each package you download or build should have help files. If you are writing data functions or developing analyses that use the functions in a package, you might want to see Help topics associated with them.

## Procedure

1. In Spotfire, open a sample DXP file.
2. From the menu, click Tools > TERR Tools.
3. Click Open TERR Language Reference.
   Note: The language reference is included in the installation. The links to the technical guides and readme files open these documents on the TIBCO documentation website for Spotfire Enterprise Runtime for R.
   A web browser launches and displays the landing page with links to the documentation for TERR.
4. Under Reference, click Included Packages.
5. In the resulting Available Packages page, note that your package is listed. Click its name.
6. From the resulting page, select the function for which you want help.
