+## Benchmark Folder Tools Deprecated
+All benchmark workloads have been moved to [OpenSearch Benchmark Workloads](https://github.com/opensearch-project/opensearch-benchmark-workloads/tree/main/vectorsearch). Please use OSB tool to run the benchmarks.
+
+If you are still interested in using the old tool, the benchmarks are moved to the [branch](https://github.com/opensearch-project/k-NN/tree/old-benchmarks/benchmarks).
