 More specs to come soon!
 
 ## History
 
 These test-plans historically used Testground. To read why we're now using `docker compose` instead please see: [Why we're moving away from Testground](https://github.com/libp2p/test-plans/issues/103)
 
+## Performance Benchmarking
+
+Please see the [benchmarking README](./perf#libp2p-performance-benchmarking).
