 # ssh-chat
 
-Coming real soon.
+Custom SSH server written in Go. Instead of a shell, you get a chat prompt.
+
+
+## Quick Start
+
+```
+Usage:
+  ssh-chat [OPTIONS]
+
+Application Options:
+  -v, --verbose   Show verbose logging.
+  -b, --bind=     Host and port to listen on. (0.0.0.0:22)
+  -i, --identity= Private key to identify server with. (~/.ssh/id_rsa)
+
+Help Options:
+  -h, --help      Show this help message
+```
+
+After doing `go get github.com/shazow/ssh-chat` on this repo, you should be able
+to run a command like:
+
+```
+$ ssh-chat --verbose --bind ":2022" --identity ~/.ssh/id_dsa
+```
+
+To bind on port 22, you'll need to make sure it's free (move any other ssh
+daemons to another port) and run ssh-chat as root (or with sudo).
+
+
+## Developing
+
+If you're developing on this repo, there is a handy Makefile that should set
+things up with `make run`.
