+# Qinglong Python API (QLAPI) Documentation
+
+## Overview
+
+The Qinglong Python API provides a convenient way to interact with the Qinglong system from Python scripts. The `QLAPI` object is automatically available in your Python scripts when they run within the Qinglong environment.
+
+## Availability
+
+The Python QLAPI is available starting from **version 2.8.0+**. If you're using an older version (e.g., v2.7.11), please upgrade to access these features.
+
+## Prerequisites
+
+- Qinglong version 2.8.0 or higher
+- Python 3.6 or higher
+- Running within Qinglong environment (scripts executed through Qinglong task system)
+
+## Usage
+
+The `QLAPI` object is automatically injected into your Python script's global namespace. You don't need to import anything - just use it directly:
+
+```python
+# QLAPI is automatically available
+result = QLAPI.getEnvs({"searchValue": "USER"})
+print(result)
+```

+## Complete Example
+
+```python
+"""
+Example Qinglong Python script demonstrating QLAPI usage
+"""
+
+# Get environment variables
+print("Fetching environment variables...")
+envs = QLAPI.getEnvs({"searchValue": "TOKEN"})
+print(f"Found {len(envs.get('data', []))} environment variables")
+
+# Create a new environment variable
+print("Creating new environment variable...")
+result = QLAPI.createEnv({
+    "envs": [
+        {
+            "name": "MY_TEST_VAR",
+            "value": "test_value_123",
+            "remarks": "Created by script"
+        }
+    ]
+})
+print(f"Create result: {result}")
+
+# Send notification
+print("Sending notification...")
+QLAPI.notify("Script Completed", "The script has finished executing successfully")
+
+# Send system notification
+QLAPI.systemNotify({
+    "title": "Task Report",
+    "content": f"Processed {len(envs.get('data', []))} environment variables"
+})
+
+print("Done!")
+```
+
+## Error Handling
+
+All QLAPI methods may raise exceptions if there are errors communicating with the backend. It's recommended to use try-except blocks:
+
+```python
+try:
+    envs = QLAPI.getEnvs({"searchValue": "USER"})
+    print(f"Success: {envs}")
+except Exception as e:
+    print(f"Error: {e}")
+    QLAPI.notify("Script Error", str(e))
+```
+
+## Troubleshooting
+
+### AttributeError: 'BaseApi' object has no attribute 'getEnvs'
+
+This error occurs when using an older version of Qinglong (before v2.8.0). Solutions:
+
+1. **Upgrade Qinglong**: Update to version 2.8.0 or higher
+2. **Check Installation**: Ensure `shell/preload/client.py` exists
+3. **Verify Environment**: Make sure scripts are running within Qinglong environment
+
+### Module Import Errors
+
+The QLAPI is only available when scripts run within the Qinglong environment. If you're testing locally, you won't have access to QLAPI.
+
+## Technical Details
+
+The Python QLAPI is a wrapper around the Node.js gRPC API client. When you call a method like `QLAPI.getEnvs()`:
+
+1. Python Client creates a temporary Node.js script
+2. Executes the corresponding Node.js API method
+3. Returns the JSON result back to Python
+
+This architecture ensures consistency between JavaScript and Python APIs.
