+## Run locally
+
+You can trivially update (and optionally send a PR) the results by running the benchmarks locally.
+Simply fork the repository, clone it locally and run the `.\update.ps1` script from a `pwsh` prompt.
+
+The only requirement is to have `jq` installed and available in your `PATH`.
