 The motivation for this module is to provide a generic server which
 can be developed and scaled over time. Ultimately the running process
 is a large "monolith" server which can be composed of many smaller
 "plugins", which can be connected together loosely.
 
+## Running the server
+
+The easiest way to run an nginx reverse proxy server, with an API to 
+manage nginx configuration, is through docker:
+
+```bash
+docker run -p 8080:80 ghcr.io/mutablelogic/go-server
+```
+
+This will start a server on port 8080. Use API commands to manage the
+nginx configuration. Ultimately you'll want to develop your own plugins
+and can use this image as the base image for your own server.
