 # Dora Llama factory recorder
 
 Experimental node for recording for training llama based model.
+
+## Get started
+
+- Git clone llama-factory:
+
+```bash
+git clone https://github.com/hiyouga/LLaMA-Factory --depth 1 $HOME
+```
+
+- Replace your AI model node with llama-factory-recorder node.
+
+Example:
+
+```yaml
+- id: dora-qwenvl-recorder
+  build: pip install -e ../../node-hub/llama-factory-recorder
+  path: llama-factory-recorder
+  inputs:
+    image_right: reachy/image_right
+    ground_truth: key-interpolation/text
+  outputs:
+    - text
+  env:
+    DEFAULT_QUESTION: Respond to people. # Prompt to use
+    LLAMA_FACTORY_ROOT_PATH: $HOME/LLaMA-Factory # path to llama factory
+```
+
+- Run your dataflow and at the end of the run you will find your data within the llama factory folder.
+- Modify `llama-factory/examples/train_lora/qwen2vl_lora_sft.yaml` so that the dataset is the one you want to use,
+
+```yaml,diff
+- dataset: mllm_demo,identity  # video: mllm_video_demo
++ dataset: dora_demo_1,identity`
+```
+
+- You can also choose the 2B model instead of the 7B model with
+
+```yaml,diff
+- model_name_or_path: Qwen/Qwen2-VL-7B-Instruct
++ model_name_or_path: Qwen/Qwen2-VL-2B-Instruct
+```
+
+- Then
+
+```bash
+llamafactory-cli train examples/train_lora/qwen2vl_lora_sft.yaml
+```
