 ### Running Bender
 
 ```bash
-# Using the module
-python -m bender
+# Copy and fill in your environment variables first
+cp .env.example .env
 
-# Or with environment variables inline
-SLACK_BOT_TOKEN=xoxb-... SLACK_APP_TOKEN=xapp-... ANTHROPIC_API_KEY=sk-ant-... python -m bender
+# Run with uv (loads .env into the process environment)
+uv run --env-file .env python -m bender
+
+# Or, if the venv is activated and vars are exported in your shell
+python -m bender
 ```
 
+> **Note:** Bender does not auto-load `.env` — the variables must be present in the process environment. `uv run --env-file .env` handles this for you; otherwise export them in your shell first.

 Bender starts both the Slack Socket Mode handler and the FastAPI HTTP server concurrently.
