 Ok, we need to make some changes to the repository.
 
-## 1. Adjust the Application
-
-Remove the app's exposed ports, and connect to the proxy's network:

-```yaml title="app/compose.yaml" hl_lines="5-11 13-15"
-services:
-  caddy:
-    build:

-        aliases:
-          - ${COMPOSE_PROJECT_NAME}_caddy
-
-networks:
-  proxy_default:
-    external: true
-```
-
-What's changed?
-
-1. The exposed ports were removed.
-1. Caddy's site address has changed to `:80` (The application layer no longer
-   handles TLS).
-1. We connect to the proxy's network, so the proxy can direct traffic to the
-   app.
-1. A container alias was added. This alias allows the proxy to target this
-   container, while still allowing Docker to manage the container name.
-
-The `CADDY_SITE_ADDRESS` environment variable can be removed from the override
-file.
