Stepwise Test in Gatling


I am very new to Gatling I am trying to find a way to create step wise load scenario on Gatling, e.g. 10 users at once and execute the api for 10 minutes then
10 new users at once and execute the api for another 10 minutes. Can somebody help in that. I have googled it but could not find an answer.



take a look at Stair Case Test here:


Thanks for pointing me there, I checked the script, It would have been a delight if I knew what is happening in it or there was some explanation about the steps.

I copy and paste the code and please see the attachment for my execution.
