 If your container expose more than one service on different ports and those services need to be proxied, you'll need to use the `VIRTUAL_HOST_MULTIPORTS` environment variable. This variable takes virtual host, path, port and dest definition in YAML (or JSON) form, and completely override the `VIRTUAL_HOST`, `VIRTUAL_PORT`, `VIRTUAL_PATH` and `VIRTUAL_DEST` environment variables on this container.
 
+The YAML syntax should be easier to write on Docker compose files, while the JSON syntax can be used for CLI invocation.
