+### Shape Generation Options
+- `custom`: Manually specify shapes as a list of [m, k, n] dimensions
+  ```yaml
+  matrix_shapes:
+    - name: "custom"
+      shapes: [
+        [1024, 1024, 1024],  # [m, k, n]
+        [2048, 4096, 1024]
+      ]
+  ```
+
+- `llama`: Use LLaMa 2 70B single-node weight shapes (assumes fused attn.wqkv and ffn.w13)
+  - Generates shapes for: "attn.wqkv", "attn.w0", "ffn.w13", "ffn.w2"
+  ```yaml
+  matrix_shapes:
+    - name: "llama"
+  ```
+
+- `pow2`: Generate shapes with dimensions that are powers of 2
+  - Parameters:
+    - `min_power`: Minimum power of 2 (default: 10, which is 1024)
+    - `max_power`: Maximum power of 2 (default: 14, which is 16,384)
+  ```yaml
+  matrix_shapes:
+    - name: "pow2"
+      min_power: 10  # 2^10 = 1024
+      max_power: 12  # 2^12 = 4096
+  ```
+
+- `pow2_extended`: Generate shapes with dimensions that are powers of 2 and powers of 2 + half
+  - Parameters:
+    - `min_power`: Minimum power of 2 (default: 10, which is 1024)
+    - `max_power`: Maximum power of 2 (default: 14, which is 16,384)

+      max_power: 11
+  ```
+
+- `sweep`: Generate a sweep of shapes with different powers of 2 for M, K, N dimensions
+  - Parameters:
+    - `min_power`: Minimum power of 2 (default: 8, which is 256)
+    - `max_power`: Maximum power of 2 (default: 15, which is 32,768)
+  - Note: This generates all combinations of M, K, N dimensions, which can be a large number of shapes
+  ```yaml
+  matrix_shapes:
+    - name: "sweep"
+      min_power: 8  # 2^8 = 256

 ## Configuration Options
 
+### Profiling Options
+- `enable_profiler`: Enable standard PyTorch profiling (default: false)
+- `enable_memory_profiler`: Enable CUDA memory profiling (default: false)
+  - Only works when device is set to "cuda"
+  - Generates memory snapshots before and after inference
+  - Creates visualizations of memory usage
+  - Outputs are saved in the memory_profiler subdirectory
+
 ### Quantization Methods
 Currently, quantization string is in same format as the one being passed in llama/generate.py.
 - `baseline`: No quantization
