The Alice Gallery download (alice.org)

I downloaded the Faerie Terrain from the Alice Gallery at alice.org.
I unzipped it. But now I'm at a loss as to what I need to do to
add it to an alice world.

Can someone point me in the right direction??

Don't unzip the file. Instead rename the extension from ".zip" to ".a2c" and put the file in your local gallery. Your path should be something like this:

C:\Alice\Required\gallery\Fantasy\Faeries

Then from inside Alice click "add objects" and navigate to the faeries folder, then click on the terrain to add it to your world.
