+
+#### Local engine

+
+| ENV | Default | Description |
+|-----|---------|-------------|
+| `DOCLING_SERVE_ENG_LOC_NUM_WORKERS` | 2 | Number of workers/threads processing the incoming tasks. |

+
+| ENV | Default | Description |
+|-----|---------|-------------|
+| `DOCLING_SERVE_ENG_KFP_ENDPOINT` |  | Must be set to the Kubeflow Pipeline endpoint. When using the in-cluster deployment, make sure to use the cluster endpoint, e.g. `https://NAME.NAMESPACE.svc.cluster.local:8888`  |
+| `DOCLING_SERVE_ENG_KFP_TOKEN` |  | The authentication token for KFP. For in-cluster deployment, the app will load automatically the token of the ServiceAccount. |
+| `DOCLING_SERVE_ENG_KFP_CA_CERT_PATH` |  | Path to the CA certificates for the KFP endpoint. For in-cluster deployment, the app will load automatically the internal CA. |
+| `DOCLING_SERVE_ENG_KFP_SELF_CALLBACK_ENDPOINT` |  | If set, it enables internal callbacks providing status update of the KFP job. Usually something like `https://NAME.NAMESPACE.svc.cluster.local:5001/v1alpha/callback/task/progress`. |
+| `DOCLING_SERVE_ENG_KFP_SELF_CALLBACK_TOKEN_PATH` |  | The token used for authenticating the progress callback. For cluster-internal workloads, use `/run/secrets/kubernetes.io/serviceaccount/token`. |

+<details>
+<summary><b>Steps</b></summary>
+
+1. Check driver version and which GPU you want to use (0/1/2/3.. and update [compose-gpu.yaml](./deploy-examples/compose-gpu.yaml) file or use `count: all`)
+
+    ```sh
+    nvidia-smi
+    ```
+
+2. Check if the NVIDIA Container Toolkit is installed/updated
+
+    ```sh
+    # debian
+    dpkg -l | grep nvidia-container-toolkit
+    ```
+
+    ```sh
+    # rhel
+    rpm -q nvidia-container-toolkit
+    ```
+
+    NVIDIA Container Toolkit install steps can be found here:
+
+    <https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/latest/install-guide.html>
+
+3. Check which runtime is being used by Docker
+
+    ```sh
+    # docker
+    docker info | grep -i runtime
+    ```
+
+4. If the default Docker runtime changes back from 'nvidia' to 'default' after restarting the Docker service (optional):
+
+    Backup the daemon.json file:
+
+    ```sh
+    sudo cp /etc/docker/daemon.json /etc/docker/daemon.json.bak
+    ```
+
+    Update the daemon.json file:
+
+    ```sh
+    echo '{
+      "runtimes": {
+        "nvidia": {
+          "path": "nvidia-container-runtime"
+        }
+      },
+      "default-runtime": "nvidia"
+    }' | sudo tee /etc/docker/daemon.json > /dev/null
+    ```
+
+    Restart the Docker service:
+
+    ```sh
+    sudo systemctl restart docker
+    ```
+
+    Confirm 'nvidia' is the default runtime used by Docker by repeating step 3.
+
+5. Run the container:
+
+    ```sh
+    docker compose -f docs/deploy-examples/compose-gpu.yaml up -d
+    ```

+### Picture description options
+
+When the picture description enrichment is activated, users may specify which model and which execution mode to use for this task. There are two choices for the execution mode: _local_ will run the vision-language model directly, _api_ will invoke an external API endpoint.
+
+The local option is specified with:
+
+```jsonc
+{
+  "picture_description_local": {
+    "repo_id": "",  // Repository id from the Hugging Face Hub.
+    "generation_config": {"max_new_tokens": 200, "do_sample": false},  // HF generation config.
+    "prompt": "Describe this image in a few sentences. ",  // Prompt used when calling the vision-language model.
+  }
+}
+```
+
+The possible values for `generation_config` are documented in the [Hugging Face text generation docs](https://huggingface.co/docs/transformers/en/main_classes/text_generation#transformers.GenerationConfig).
+
+The api option is specified with:
+
+```jsonc
+{
+  "picture_description_api": {
+    "url": "",  // Endpoint which accepts openai-api compatible requests.
+    "headers": {},  // Headers used for calling the API endpoint. For example, it could include authentication headers.
+    "params": {},  // Model parameters.
+    "timeout": 20,  // Timeout for the API request.
+    "prompt": "Describe this image in a few sentences. ",  // Prompt used when calling the vision-language model.
+  }
+}
+```
+
+Example URLs are:
+
+- `http://localhost:8000/v1/chat/completions` for the local vllm api, with example `params`:
+  - the `HuggingFaceTB/SmolVLM-256M-Instruct` model
+
+    ```json
+    {
+        "model": "HuggingFaceTB/SmolVLM-256M-Instruct",
+        "max_completion_tokens": 200,
+    }
+    ```
+  
+  - the `ibm-granite/granite-vision-3.2-2b` model
+
+    ```json
+    {
+        "model": "ibm-granite/granite-vision-3.2-2b",
+        "max_completion_tokens": 200,
+    }
+    ```
+
+- `http://localhost:11434/v1/chat/completions` for the local ollama api, with example `params`:
+  - the `granite3.2-vision:2b` model
+
+    ```json
+    {
+        "model": "granite3.2-vision:2b"
+    }
+    ```  
+
+Note that when using `picture_description_api`, the server must be launched with `DOCLING_SERVE_ENABLE_REMOTE_SERVICES=true`.
