 4. start openai compatible server:
 ```
-./llama-server -ngl 35 -m Llama-3-8b-function-calling-alpha-v1.gguf   --port 1234 --host 0.0.0.0  -c 16000 --chat-template llama3

 ```
 
-5. That's it! MAKE SURE you turn `stream` OFF when making api calls to the server, as the streaming feature is not supported yet. And we will support streaming too soon.
+5. Test to make sure the server is available:
+```bash
+curl localhost:1234/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer tokenabc-123" \
+  -d '{
+    "model": "rubra-model",
+    "messages": [
+      {
+        "role": "system",
+        "content": "You are a helpful assistant."
+      },
+      {
+        "role": "user",
+        "content": "hello"
+      }
+    ]
+  }'
+```
+
+6. Try a python function calling example:
+```python
+from openai import OpenAI
+client = OpenAI(api_key="123", base_url = "http://localhost:1234/v1/")
+
+tools = [
+  {
+    "type": "function",
+    "function": {
+      "name": "get_current_weather",
+      "description": "Get the current weather in a given location",
+      "parameters": {
+        "type": "object",
+        "properties": {
+          "location": {
+            "type": "string",
+            "description": "The city and state, e.g. San Francisco, CA",
+          },
+          "unit": {"type": "string", "enum": ["celsius", "fahrenheit"]},
+        },
+        "required": ["location"],
+      },
+    }
+  }
+]
+messages = [{"role": "user", "content": "What's the weather like in Boston today?"}]
+completion = client.chat.completions.create(
+  model="rubra-model",
+  messages=messages,
+  tools=tools,
+  tool_choice="auto"
+)
+
+print(completion)
+```
+
+The output should look like this:
+```
+ChatCompletion(id='chatcmpl-EmHd8kai4DVwBUOyim054GmfcyUbjiLf', choices=[Choice(finish_reason='tool_calls', index=0, logprobs=None, message=ChatCompletionMessage(content=None, role='assistant', function_call=None, tool_calls=[ChatCompletionMessageToolCall(id='e885974b', function=Function(arguments='{"location":"Boston"}', name='get_current_weather'), type='function')]))], created=1719528056, model='rubra-model', object='chat.completion', system_fingerprint=None, usage=CompletionUsage(completion_tokens=29, prompt_tokens=241, total_tokens=270))
+```
+
+That's it! MAKE SURE you turn `stream` OFF when making api calls to the server, as the streaming feature is not supported yet. And we will support streaming too soon.
