Clay is the filesystem and typed revision-control vane. It can be thought of as a continuously synced git. Clay handles file-change events and maps them from Arvo to Unix and vice versa.

A common way to use Clay is to create a pier, a directory that exists in and is visible in Unix. Changes are automatically recorded from Urbit to the Unix directory and vice versa. Just set it and forget it!

Clay is located at /base/sys/vane/clay.hoon within Arvo.
