 To call models hosted behind an openai proxy, make 2 changes:
 
-1. Put `openai/` in front of your model name, so litellm knows you're trying to call an openai-compatible endpoint. 
+1. For `/chat/completions`: Put `openai/` in front of your model name, so litellm knows you're trying to call an openai `/chat/completions` endpoint. 
+
+2. For `/completions`: Put `text-completion-openai/` in front of your model name, so litellm knows you're trying to call an openai `/completions` endpoint. 
 
 2. **Do NOT** add anything additional to the base url e.g. `/v1/embedding`. LiteLLM uses the openai-client to make these calls, and that automatically adds the relevant endpoints.

+# OpenAI (Text Completion)
+
+LiteLLM supports OpenAI text completion models
+
+### Required API Keys
+
+```python
+import os 
+os.environ["OPENAI_API_KEY"] = "your-api-key"
+```
+
+### Usage
+```python
+import os 
+from litellm import completion
+
+os.environ["OPENAI_API_KEY"] = "your-api-key"
+
+# openai call
+response = completion(
+    model = "gpt-3.5-turbo-instruct", 
+    messages=[{ "content": "Hello, how are you?","role": "user"}]
+)
+```
+
+### Usage - LiteLLM Proxy Server
+
+Here's how to call OpenAI models with the LiteLLM Proxy Server
+
+### 1. Save key in your environment
+
+```bash
+export OPENAI_API_KEY=""
+```
+
+### 2. Start the proxy
