+## Convert to Docker Compose format
 
-TBD
+Uncloud supports the [Compose file format](https://docs.docker.com/reference/compose-file/) for defining services. This
+allows you to version control your deployments, share configurations with your team, and deploy complex multi-service
+applications with a single command.
+
+Let's create a `compose.yaml` file in your current directory for the `excalidraw` service we just deployed.
+
+```yaml title="compose.yaml"
+services:
+  excalidraw:
+    image: excalidraw/excalidraw
+    x-ports:
+      - 80/https
+```
+
+:::info note
+
+The `x-ports` key is an Uncloud-specific extension to the Compose file format. It allows you to specify ports that
+should be published as HTTP(S) endpoints. Uncloud automatically configures the reverse proxy (Caddy) to route traffic to
+these ports.
+
+:::
+
+Now deploy it:
+
+```shell
+uc deploy
+```
+
+```
+Services are up to date.
+```
+
+Since `excalidraw` service is already running with the same configuration, Uncloud recognises there's nothing to change.
+We've successfully converted our deployment created with `uc run` to a Compose file.
 
 ## Use your own domain
 
-TBD
+Want to use your own domain, for example, `excalidraw.example.com` instead of `excalidraw.7za6s7.cluster.uncloud.run`?
+
+Add a CNAME record `excalidraw.example.com` in your DNS provider (Cloudflare, Namecheap, etc.) pointing to
+`excalidraw.7za6s7.cluster.uncloud.run`. Alternatively, you can add an A record pointing to your server's IP.
+
+Then update the published port `80/https` in `compose.yaml` to use your domain:
+
+```yaml title="compose.yaml"
+...
+x-ports:
+  - excalidraw.example.com:80/https
+```
+
+Finally, deploy the changes:
+
+```shell
+uc deploy
+```
+
+```
+Deployment plan:
+- Deploy service [name=excalidraw]
+  - machine-dc3c: Run container [image=excalidraw/excalidraw]
+  - machine-dc3c: Remove container [name=excalidraw-azpc]
+
+Do you want to continue?

+ ✔ Container excalidraw-azpc on machine-dc3c  Removed                       3.4s

+
+Notice how Uncloud performed a **zero-downtime deployment** — it started the new container with the updated
+configuration before removing the old one. Your service stayed available throughout the update.
+
+Give it a moment for Caddy to obtain a TLS certificate, then visit https://excalidraw.example.com.
