+## Pushing to Gitea Registry
+
+If your Gitea instance has a container registry, push the built image:
+
+```bash
+./scripts/docker_push.sh

+
+This reads your Gitea credentials from `credentials.toml` (registry_url, username, token) and pushes to `https://git.cozyair.dev/ed/manual_slop:latest`.

 ## Running the Container
 
 Edit `docker-compose.yml` to set your volume paths and provider keys (via `.env` file or environment).

+## Pulling from Gitea Registry on Unraid
+
+If you pushed the image to Gitea's container registry, pull it on Unraid:
+
+```bash
+# Login to Gitea registry
+docker login git.cozyair.dev -u ed
+
+# Pull the image
+docker pull git.cozyair.dev/ed/manual_slop:latest
+
+# Run the container
+docker run -d \
+  --name manual_slop \
+  -p 8999:8999 \

+  -v /mnt/user/projects:/projects \
+  -v /mnt/user/appdata/manual_slop:/config \
+  git.cozyair.dev/ed/manual_slop:latest
+```
+
+Or use `docker-compose.yml` after editing the image name:
+```yaml
+image: git.cozyair.dev/ed/manual_slop:latest
+```
+
 ## Updating
 
 ```bash
 git pull
 docker build -t manual_slop:latest .
+./scripts/docker_push.sh  # if using Gitea registry
 docker compose up -d
