 Hermes Agent supports full voice interaction across CLI and messaging platforms. Talk to the agent using your microphone, hear spoken replies, and have live voice conversations in Discord voice channels.
 
+## Prerequisites
+
+Before using voice features, make sure you have:
+
+1. **Hermes Agent installed** — `pip install hermes-agent` (see [Getting Started](../../getting-started.md))
+2. **An LLM provider configured** — set `OPENAI_API_KEY`, `OPENAI_BASE_URL`, and `LLM_MODEL` in `~/.hermes/.env`
+3. **A working base setup** — run `hermes` to verify the agent responds to text before enabling voice
+
+:::tip
+The `~/.hermes/` directory and default `config.yaml` are created automatically the first time you run `hermes`. You only need to create `~/.hermes/.env` manually for API keys.
