 Server side for [tty-share](https://github.com/elisescu/tty-share).
 
+
+## Docker
+
+The server can be built into a docker image as follows:
+
+    docker build -t tty-server .
+
+To run the container, type:
+
+    docker run \
+      -p 6543:6543 -p 5000:5000 \
+      -e URL=http://localhost:5000 \
+      --cap-drop=all --rm \
+      tty-server
+
+where you can replace `URL` by whatever will be the publicly visible URL of the server.
+
+After this, clients can be connected as follows:
+
+    tty-share -useTLS=false -server localhost:6543
+
+In the above command, 6543 is the default port where `tty-server` listens for
+incoming shares (i.e. `tty-share` clients), and 5000 is the port of the web
+interface through which remote users can connect. You can override the
+defaults by specifying a different port mapping on the command line, e.g.
+`-p 7654:6543 -p 80:5000` to listen on `7654` and serve on `80`.
