 `LLAMA_BASE_URL` / `PAPERLESS_BASE_URL` must be reachable **from inside the container** (use `host.docker.internal` on Docker Desktop, or your LAN IP, not `127.0.0.1` for services on the host).
 
-CI: on push to `main`, [.gitea/workflows/build-docker.yml](.gitea/workflows/build-docker.yml) builds and pushes using the same secrets pattern as your other Gitea repos (`DOCKER_REGISTRY`, `DOCKER_USERNAME`, `DOCKER_PASSWORD`). For Docker Hub, set `DOCKER_REGISTRY` to `docker.io` (or leave per your runner docs).
+### Docker Compose
+
+Save as `compose.yaml` (any directory with your `.env`):
+
+```yaml
+services:
+  notebook-tools:
+    image: git.danhenry.dev/daniel/notebook-tools:latest
+    ports:
+      - "8080:8080"
+    env_file:
+      - .env
+    # Lets the container reach services bound on the host (e.g. llama on :9292).
+    # Linux: requires Docker 20.10+ / Compose v2; omit on Docker Desktop if already available.
+    extra_hosts:
+      - "host.docker.internal:host-gateway"
+```
+
+```bash
+docker compose pull && docker compose up
+```
+
+Log in to `git.danhenry.dev` first if the registry requires auth: `docker login git.danhenry.dev`.
+
+For llama running **on the host**, set in `.env`:
+
+```bash
+LLAMA_BASE_URL="http://host.docker.internal:9292"
+```
+
+`PAPERLESS_BASE_URL` can stay a normal `https://…` URL if the container has network access to it.
+
+CI: on push to `main`, [.github/workflows/build-docker.yml](.github/workflows/build-docker.yml) builds and pushes using the same secrets pattern as your other Gitea repos (`DOCKER_REGISTRY`, `DOCKER_USERNAME`, `DOCKER_PASSWORD`). For Docker Hub, set `DOCKER_REGISTRY` to `docker.io` (or leave per your runner docs).
