 You will be assigned a URL similar to `qdci.sub.example.com:1234`.
 
 If your server is acting as a reverse proxy (i.e. nginx) and is able to listen on port 80, then you do not need the `:1234` part of the hostname for the `lt` client.
+
+## Deploy
+
+You can deploy your own localtunnel server using the prebuilt docker image.
+
+**Note** This assumes that you have a proxy in front of the server to handle the http(s) requests and forward them to the localtunnel server on port 3000. You can use our [localtunnel-nginx](https://github.com/localtunnel/nginx) so accomplish this.
+
+If you do not want ssl support for your own tunnel (not recommended), then you can just run the below with `--port 80` instead.
+
+```
+docker run -d \
+    --restart always \
+    --name localtunnel \
+    --net host \
+    defunctzombie/localtunnel-server:latest --port 3000
+```
