-Repository for the io_moon mod.
\ No newline at end of file
+This mod replaces the default terrain with Io, a volcanic moon of Jupiter. Io is more volcanic than Earth. Lava is everywhere, but it is more common underground. Mountains, or should I say volcanos, are coated with lava. There are lava lakes, too.
