+data. 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

+When you first run the server, a "root" API token is created which is used to
+authenticate API requests. You can find this token in the log output or by running
+the following command:
+
+```bash
+docker exec <container-id> cat /data/tokenauth.json

-## Running the Server
-
-You can run the server:
-
-  1. With a HTTP server over network: You can specify TLS key and certificate
-    to serve requests over a secure connection;
-  2. With a HTTP server with FastCGI over a unix socket: You would want to do
-    this if the server is behind a reverse proxy such as nginx.
-  3. In a docker container, and expose the port outside the container. The docker
-     container targets `amd64` and `arm64` architectures on Linux.
