 This document explains the key configuration parameters that can be modified for Wall-X training.
 
+## Quick Start Checklist
+1. **Update run.sh**: Set `code_dir` and `config_path` to your actual paths
+2. **Configure GPUs**: Set `CUDA_VISIBLE_DEVICES` for your available GPUs  
+3. **Update config paths**: Replace all `/path/to/` placeholders in `config_qact.yml` with actual paths
+4. **Configure robot**: Set `dof_config` and `agent_pos_config` for your robot
+5. **Set dataset**: Choose appropriate `repo_id` for your dataset
+6. **Adjust batch size**: Set `batch_size_per_gpu` based on GPU memory
+7. **Run training**: Execute `bash ./workspace/lerobot_example/run.sh`
+
 ## Enable FAST tokenizer
 To fine-tune using the FAST tokenizer, please download the repository and update the `action_tokenizer_path`. Make sure to set `use_fast_tokenizer` to `true`:
 ```bash
 git clone https://huggingface.co/physical-intelligence/fast
 ```
