future we'll stop reading those.

-# Proxy
-#
-# **Experimental** [kamal-proxy](http://github.com/basecamp/kamal-proxy) is a
-# custom built specifically for Kamal. It will replace Traefik in Kamal v2.0,
-# but currently is available as an experimental feature.
-#
-# When this is enabled, the proxy will be started on the hosts listed under the hosts key.
-# In addition, the kamal traefik command will be disabled and replaced by kamal proxy.
-#
-# The kamal proxy command works identically to kamal traefik on hosts that have not
-# been included. It will also handle switching between Traefik and kamal-proxy when you
-# run kamal proxy reboot.
-
-# Limitations
-#
-# Currently the proxy will run on ports 80 and 443 and will bind to those
-# ports on the host.
-#
-# There is no way to set custom options for `docker run` when booting the proxy.
-#
-# If you have custom Traefik configuration via labels or boot arguments they may
-# not have an equivalent in kamal-proxy.
-
-# Proxy settings
-#
-# The proxy is configured in the root configuration under `traefik`. These are
-# options that are set when deploying the application, not when booting the proxy
-#
-# They are application specific, so are not shared when multiple applications
-# with the same proxy.

-  # This is a temporary setting and will be removed when we full switch to kamal-proxy

-  # Host
-  #
-  # This is the host that will be used to serve the app. By setting this you can run
-  # multiple apps on the same server sharing the same instance of the proxy.

-  # if this is not set, then all requests will be forwarded, except for matching
