AWS Landing Accelerator

I am trying to deploy a Landing zone from my CLI using the LZA cloudformation tempelate and the AWS github repo: https://github.com/awslabs/landing-zone-accelerator-on-aws#aws-acceleratorconfig and I am stuck at a parameter field which I do not know what it is refering to. I have made the section bold (AcceleratorQualifier,ParameterValue=<Accelerator_Qualifier>), I would appreciate it if someone could explain to me what value I need to input in that section. Many Thanks
