+# OpenAI Proxy Servers (ChatCompletion)
+
+LiteLLM allows you to call your OpenAI ChatCompletion proxy server
+
+
+### API KEYS
+No api keys required
+
+### Example Usage
+
+#### Pre-Requisites
+Ensure your proxy server has the following route
+
+```python
+@app.route('/chat/completions', methods=["POST"])
+def chat_completion():
+  print("got request for chat completion")
+
+```
+
+In order to use your custom OpenAI Chat Completion proxy with LiteLLM, ensure you set
+
+* `api_base` to your proxy url, example "https://openai-proxy.berriai.repl.co"
+* `custom_llm_provider` to `openai` this ensures litellm uses the `openai.ChatCompletion` to your api_base
+
+```python
+
+from litellm import completion
+
+## set ENV variables
+os.environ["OPENAI_API_KEY"] = "set it, but it's not used"
+
+messages = [{ "content": "Hello, how are you?","role": "user"}]
+
+response = completion(
+    model="command-nightly", 
+    messages=[{ "content": "Hello, how are you?","role": "user"}],
+    api_base="https://openai-proxy.berriai.repl.co",
+    custom_llm_provider="openai"
+    temperature=0.2,
+    max_tokens=80,
+)
+print(response)
+```
