+To successfully use Tools (Functions), you need to specify a provider and a model that support them. As of the writing of this README, the provider that supports them is OpenAI, with models `gpt-3.5-turbo-1106` and `gpt-4-1106-preview`:
+
+```yaml
+provider:
+  id: openai
+  credentials:
+    address: ENV/OPENAI_API_ADDRESS
+    access-token: ENV/OPENAI_API_KEY
+  settings:
+    user: ENV/NANO_BOTS_END_USER
+    model: gpt-4-1106-preview
+```
