+---
+
+## Getting an API Key
+
+1. **Sign in:** Go to the [TrustedRouter console](https://trustedrouter.com/console/api-keys).
+2. **Create an API key:** Create a new key for Zoo Code.
+3. **Copy the key:** Store it securely. The raw key is only shown once.

+2. **Select Provider:** Choose "OpenRouter" from the "API Provider" dropdown.
