Is there a detailed explanation for starkStruct?

  const starkStruct = {
    "nBits": 10, 
    "nBitsExt": 11, 
    "nQueries": 128, 
    "verificationHashType": "GL", 
    "steps": [ 
      {"nBits": 11}, 
      {"nBits": 5}, 
      {"nBits": 3}, 
      {"nBits": 1} 
    ]
  };

I think nBits and nBitsExt are corresponding to domain field size and extension field size, GL means Goldilocks field.

What about nQueries and steps?

From what I understand, nQueries refers to the number of query phases of FRI, while each of the steps are the reduction factors.
