+First run: create caddy network for other stacks to attach to:
+```sh
+docker network create caddy
+```
+
+Start the proxy
+```sh
+docker compose up
+```
+
+---
+
+Integrating with other stacks:
+
+Add the external network:
+```yml
+networks:
+  caddy:
+    external: true

+
+Add the `caddy` network and labels to the services you want to proxy:
+```sh
+services:
+  app:
+    networks:
+      - default
+      - caddy
+    labels:
+      caddy: example.localhost # The domain this app should use.
+      caddy.reverse_proxy: "{{upstreams 80}}" # The internal port that the container is listening on.
