+### Running with Authentication
+GenAI-Perf can benchmark secure endpoints such as OpenAI, which requires API
+key authentication. To do so, you can add your API key directly in the command.
+At the end of your command, append the below flags. Replace the key with your
+API key. The `--` flag allows arguments to pass directly into Perf Analyzer in
+superuser mode. The `-H` flag is used to add HTTP headers.

+```bash
+-- -H "Authorization: Bearer ${OPENAI_API_KEY}" -H "Accept: text/event-stream"
