# dmsg


`dmsg` is a distributed messaging system comprised of three types of services:
- `dmsg.Client` represents a user/client that wishes to use the dmsg network to establish `dmsg.Session`s and `dmsg.Stream`s.
- `dmsg.Server` represents a service that proxies `dmsg.Stream`s between `dmsg.Client`s.
