## Service Description

in service implementation, you can implement the optional `describe()` method to provide service documentation. This description is used by the admin embedded to describe the service, and to provide a standard way to interact with it.

a Web interface permit to use it and run implemented methods.

### Implementing a describe method in the service

You can implement the optional `describe()` method to provide service documentation:

```python
def describe():
    return json.dumps({
        "name": "temperature",
        "description": "Temperature monitoring service",
        "methods": {
            "get_temperature": {
                "name": "get_temperature",
                "description": "Get current temperature reading",
                "parameters": [],
                "returns": "json"
            },
            "set_unit": {
                "name": "set_unit",
                "description": "Set temperature unit (Celsius/Fahrenheit)",
                "parameters": [
                    {
                        "name": "unit",
                        "description": "Temperature unit to use",
                        "required": True,
                        "default_value": None,
                        "parameter_type": "string"
                    }
                ],
                "returns": "json"
            }
        }
    })

# Don't forget to register the describe function
server.register_function(describe)
```
