+## Quick Start
+Use just 2 lines of code, to instantly log your responses **across all providers** with Phoenix
+
+You can also use the instrumentor option instead of the callback, which you can find [here](https://docs.arize.com/phoenix/tracing/integrations-tracing/litellm).
+
+```python
+litellm.callbacks = ["arize_phoenix"]
+```
+```python
+import litellm
+import os
+
+os.environ["PHOENIX_API_KEY"] = "" # Necessary only using Phoenix Cloud
+os.environ["PHOENIX_COLLECTOR_HTTP_ENDPOINT"] = "" # The URL of your Phoenix OSS instance
+# This defaults to https://app.phoenix.arize.com/v1/traces for Phoenix Cloud
+
+# LLM API Keys
+os.environ['OPENAI_API_KEY']=""
+
+# set arize as a callback, litellm will send the data to arize
+litellm.callbacks = ["phoenix"]
+ 
+# openai call
+response = litellm.completion(
+  model="gpt-3.5-turbo",
+  messages=[
+    {"role": "user", "content": "Hi 👋 - i'm openai"}
+  ]
