Urbit is a personal server stack built from scratch. This repository contains Urbit's runtime environment, the lowest layer of the Urbit stack, which includes the Nock virtual machine, I/O drivers, event log, and snapshotting system.
For basic Urbit usage instructions, head over to urbit.org. For a high-level overview of the salient aspects of Urbit's architecture, visit developers.urbit.org. You might also be interested in joining the urbit-dev mailing list.
