+│   ├── agent_browser/                # Pure Python browser agent
+│   └── browser_use_fullstack_runtime/ # Full-stack runtime version
+├── deep_research/                    # Deep research examples
+│   ├── agent_deep_research/

+# 📥 Submitting a Pull Request (PR)
+
+### 1. **Directory Placement**
+- **Location**:
+  Choose an existing subdirectory (e.g., `browser_use/`、`games/`), or create a new one (update the **Example List** table in the root `README.md`)
+- **File Naming**:  
+  - Example files: `feature_description.py`(如 `chatbot_multi_turn.py`)  
+  - Test files: `test_feature_description.py`
+
+### 2. **Write a Detailed README**
+- **Subdirectory `README.md`**:  
+  Include the following to ensure reproducibility:
+  ```markdown
+  ## Example Name (e.g., Multi-turn Chatbot)
+
+  ### 📌 Description
+  Demonstrates the implementation of multi-turn conversations.
+
+  ### 📦 Dependencies
+  ```bash
+  pip install -r requirements.txt
+  ```
+  
+### 🚀 Run Command
+```bash
+python chatbot_multi_turn.py
+```
+
+
+- **Root `README.md`**:  
+Update the **Example List** table with links to new examples.
+
+### 3. **Dependency Management**
+- **Each Subdirectory Requires `requirements.txt`**:  
+List only dependencies needed for that example:
+
+```txt
+openai==0.27.0
+pandas==2.0.0
+```
+
+### 4. **Code Formatting**
+- **Install `pre-commit`**:  
+```bash
+pip install pre-commit
+pre-commit install
+pre-commit run --all-files
+# Fix any formatting errors (e.g., indentation, line length)
+```
+
+
+### PR Checklist
+- [ ] Example placed in the correct subdirectory (e.g., `browser_use/`、`games/`)
+- [ ] Subdirectory includes `README.md` and `requirements.txt`
+- [ ] Code formatted with `pre-commit`
+- [ ] New test cases cover core functionality
+- [ ] Root `README.md` updated with the new example
+- [ ] PR title is clear (e.g.,  `Add multi-turn chatbot example`)
