 ### Visualizing the results

 The `convert-results-json-to-markdown.py` helps you put the benchmarking results inside a markdown table, by formatting [descriptions.md](performance-benchmarks-descriptions.md) with real benchmarking results.
@@ -116,19 +176,6 @@ If you do not see the table, please wait till the benchmark finish running.
 The json version of the table (together with the json version of the benchmark) will be also attached to the markdown file.
 The raw benchmarking results (in the format of json files) are in the `Artifacts` tab of the benchmarking.

-The `compare-json-results.py` helps to compare benchmark results JSON files converted using `convert-results-json-to-markdown.py`.
-When run, benchmark script generates results under `benchmark/results` folder, along with the `benchmark_results.md` and `benchmark_results.json`.
-`compare-json-results.py` compares two `benchmark_results.json` files and provides performance ratio e.g. for Output Tput, Median TTFT and Median TPOT.  
-If only one benchmark_results.json is passed, `compare-json-results.py` compares different TP and PP configurations in the benchmark_results.json instead.
+#### Performance Results Comparison  

-Here is an example using the script to compare result_a and result_b with Model, Dataset name, input/output length, max concurrency and qps.
-`python3 compare-json-results.py -f results_a/benchmark_results.json -f results_b/benchmark_results.json`

+    Generate index for all wheel files.
+
+    Args:
+        whl_files (list[str]): List of wheel files (must be directly under `wheel_base_dir`).
+        wheel_base_dir (Path): Base directory for wheel files.
+        index_base_dir (Path): Base directory to store index files.
+        default_variant (str | None): The default variant name, if any.
+        alias_to_default (str | None): Alias variant name for the default variant, if any.
+        comment (str | None): Optional comment to include in the generated HTML files.
+
+    First, parse all wheel files to extract metadata.
+    We need to collect all wheel files for each variant, and generate an index for it (in a subdirectory).
+    The index for the default variant (if any) is generated in the root index directory.
+
+    If `default_variant` is provided, all wheels must have variant suffixes, and the default variant index
+    is purely a copy of the corresponding variant index, with only the links adjusted.
+    Otherwise, all wheels without variant suffixes are treated as the default variant.
+
+    If `alias_to_default` is provided, an additional alias subdirectory is created, it has the same content
+    as the default variant index, but the links are adjusted accordingly.
+
+    Index directory structure:
+        index_base_dir/ (hosted at wheels.vllm.ai/{nightly,$commit,$version}/)
+            index.html  # project list, linking to "vllm/" and other packages, and all variant subdirectories
+            vllm/
+                index.html # package index, pointing to actual files in wheel_base_dir (relative path)
+                metadata.json # machine-readable metadata for all wheels in this package
+            cpu/ # cpu variant subdirectory
