+### Container Registry Integration
+
+To facilitate pushing and pulling Docker images from a remote registry (e.g., `git.wlkns.org`), the `Makefile` and `docker-compose.yml` were updated:
+
+1.  **Makefile Configuration:**
+    *   Added `REGISTRY := git.wlkns.org` and `USERNAME := stephan` variables.
+    *   Modified the `tag` target to tag images in the format `$(REGISTRY)/$(USERNAME)/$(IMAGE_NAME):$(TAG)`.
+    *   Modified the `push` target to depend on `build` and `tag`, then push the image to the configured registry.
+
+2.  **`docker-compose.yml` Integration:**
+    *   Changed the `app` service definition to use `image: ${REGISTRY}/${USERNAME}/${IMAGE_NAME}:${TAG}` instead of `build: .`, making it pull from the registry by default.
+
+3.  **Makefile Workflow Enhancements:**
+    *   Added a `pull` target (`make pull`) to explicitly download the image from the registry.
+    *   The `up` target (`make up`) was modified to start the service using the image specified in `docker-compose.yml` (which now points to the registry).
+    *   A new `dev-up` target (`make dev-up`) was introduced for local development, which explicitly builds the image from source (`docker compose up --build -d`) before starting the service.
+    *   The `down` and `help` targets were updated accordingly.
+
+This allows for flexible deployment, supporting both local development with on-demand building and production-like environments pulling from a registry.
