+To run the `https` benchmarks, one of `autocannon` or `wrk` benchmarkers must
+be used.

 #### HTTP/2 Benchmark Requirements
 
 To run the `http2` benchmarks, the `h2load` benchmarker must be used. The
 `h2load` tool is a component of the `nghttp2` project and may be installed
 from [nghttp2.org][] or built from source.
