How to save my script into the Interstate75

Support

Hi,
I use Thonny to write my code to be executed in the interstate75.
Running the script works fine but I would like to have the code saved into the Interstate75 so it can run without a computer attached.
Is there some documentation available in order to do that?
Thanks
