In DrScheme choose "Intall .plt File" in the "File..." menu
That's it
Note: Use the HelpDesk to find the documentation. Search for the name of the collection.
On machines without DrScheme, you can use a command line interface instead. Give the path of the .plt file to either "Setup PLT" (Windows) or setup-plt (Unix).
