This commit updates the main README.md file to reflect the recent changes related to the container registry integration.

- Clarifies the difference between Starting development environment by pulling image from registry...
export IMAGE_NAME=audio-engine-hub && \
export REGISTRY=git.wlkns.org && \
export USERNAME=stephan && \
export TAG=latest && \
docker compose up -d (for registry images) and Starting development environment (local build) on port 8000... (for local builds).
- Adds a dedicated "Container Registry" section explaining the push/pull workflow.
- Updates the "Makefile Commands" section with the new , , and  targets.

-## Usage
+## Container Registry
 
-The application provides a simple API to generate speech and inspect the available engines.
+The project is configured to work with the container registry at `git.wlkns.org`.
+
+### Pushing an Image
+
+1.  **Log in to the Registry:**
+    You only need to do this once per machine.
+    ```bash
+    docker login git.wlkns.org
+    ```
+
+2.  **Push the Image:**
+    This command will build your image, tag it correctly, and push it to the registry.
+    ```bash
+    make push
+    ```
+
+### Pulling and Running an Image
+
+1.  **Pull the Image:**
+    To download the latest image from the registry:
+    ```bash
+    make pull
+    ```
+
+2.  **Run the Image:**
+    This command will start the application using the pre-built image from the registry (pulling it if necessary).
+    ```bash
+    make up
