 ### Units
 
 Never use physical properties like speed or time directly as integer or float in your code.
 Otherwise you encounter problems like this function `void setTimeout(int timeout)`. What is the unit of the argument, seconds? minutes? If you use `Duration` you see it directly in the code.
 
-```
+```cpp
+
 void setTimeout(const Duration & timeout);
 
 setTimeout(11_s); // 11 seconds
 setTimeout(5_ms); // 5 milliseconds
+
 ```
