@ -4,6 +4,12 @@ Before you start running your own experiments there are few details to take into
|
|||
account at the time of configuring your simulation. In this document we cover
|

the most important ones.

|

!!! tip
|
||||
Use [PythonAPI/examples/config.py][configlink] to configure the simulator
|
||||
from the command-line.
