+### Configure the Measurement Statistics Results
+
+The environment variable `INC_MEASUREMENT_DUMP_PATH_PREFIX` specifies the root directory where measurement statistics were saved.
+The final path is constructed by joining this root directory with the `dump_stats_path` defined in the quantization JSON file specified by the `QUANT_CONFIG` environment variable.
+
+#### Example
+
+If we download the measurements to `/path/to/vllm-fork/scripts/nc_workspace_measure_kvache`, we got below files:
+
+```bash
+user:vllm-fork$ pwd
+/path/to/vllm-fork
+user:vllm-fork$ ls -l  ./scripts/nc_workspace_measure_kvache
+-rw-r--r-- 1 user Software-SG 1949230 May 15 08:05 inc_measure_output_hooks_maxabs_0_8.json
+-rw-r--r-- 1 user Software-SG  254451 May 15 08:05 inc_measure_output_hooks_maxabs_0_8_mod_list.json
+-rw-r--r-- 1 user Software-SG 1044888 May 15 08:05 inc_measure_output_hooks_maxabs_0_8.npz
+...
+```
+
+Then, we export `INC_MEASUREMENT_DUMP_PATH_PREFIX=/path/to/vllm-fork`, and INC will parse the full as below:
+
+```
+dump_stats_path (from config): "scripts/nc_workspace_measure_kvache/inc_measure_output"
+Resulting full path: "/path/to/vllm-fork/scripts/nc_workspace_measure_kvache/inc_measure_output_hooks_maxabs_0_8.npz"
+```
+
 > [!CAUTION]
-> Before running the benchmark, make sure to update the `model_path` in the `single_16k_len_inc.sh` script.
+> Before running the benchmark, update the following variables in the single_16k_len_inc.sh script:
+> - `model_path`
+> - `QUANT_CONFIG`
+> - `INC_MEASUREMENT_DUMP_PATH_PREFIX`
