Parallel Testting using TestProject CLI

I want do parallel testing using CLI in local machine. It is a need to do it because Testproject appln sometimes under maintenance. I save individual yaml file into local memory. I successfully run yaml file using CLI. But I am not getting solution to do parallel testing on multiple YAML file and also when I am giving parameter that parameters are not taken by yaml file. So please share any documentation to do parallel testing on multiple yaml files. I read this file “TestProject Agent CLI - TestProject Documentation” but I want sample demonstration or how to create structure of multiple files to do parallel testing
