+This is the public facing service that allows `tty-share` command to create public sessions, in
+addition to local ones.
+
+`tty-proxy` will listen to the address passed by the `--back-address` flag, and any connections to
+this address from `tty-share` will create a new session (`<session-id>` that will be used to proxy
+any requests from any url path of the form `/s/<session-id>/` back over the corresponding
+`tty-share` connection. See more documentation on the
+[tty-share](https://github.com/elisescu/tty-share) project.
+
+**Note** `tty-proxy` replaces a part of the old `tty-server` which has moved inside the actual
+`tty-share` command itself. Read more
