+## Ollama

+### ⚠️ Important
+
+Remember that these models run locally, so you need to download them. If you want to use llama3, you can open the terminal and run the following command:
+
+```python
+ollama pull llama3
+```
+
+you can follow [Ollama documentation](https://github.com/ollama/ollama/blob/main/docs/openai.md) for more.
+
+### How to use this models locally using SwiftOpenAI?
+
+To use local models with an `OpenAIService` in your application, you need to provide a URL. 
+
+```swift
+let service = OpenAIServiceFactory.ollama(baseURL: "http:https://localhost:11434")
+```
+
+Then you can use the completions API as follows:
+
+```swift
+let prompt = "Tell me a joke"
+let parameters = ChatCompletionParameters(messages: [.init(role: .user, content: .text(prompt))], model: .custom("llama3"))
+let chatCompletionObject = service.startStreamedChat(parameters: parameters)
+```
