 ## Configuration Options
 
+### Shape Generation Options
+- `custom`: Manually specify shapes as a list of [m, k, n] dimensions
+- `llama`: Use LLaMa 2 70B single-node weight shapes (assumes fused attn.wqkv and ffn.w13)
+- `pow2`: Generate shapes with dimensions that are powers of 2 (e.g., 1024, 2048, 4096, etc.)
+- `pow2_extended`: Generate shapes with dimensions that are powers of 2 and powers of 2 + half (e.g., 1024, 1536, 2048, 3072, etc.)
+- `sweep`: Generate a sweep of shapes with different powers of 2 for M, K, N dimensions
+
 ### Quantization Methods
 Currently, quantization string is in same format as the one being passed in llama/generate.py.
 - `baseline`: No quantization
