 - Callback mechanism for handling stream content
 - Supports OpenAI Functions
 
+## 🤔 Common use-cases
+
+The main goal of this repository is to encourage you to use streaming to speed up the responses from the model.
+Among the use-cases for this library, you can:
+
+- **Improve the UX of your app** - by utilizing Streaming you can show end-users responses much faster than waiting for
+  the final response.
+- **Speed up LLM chains/pipelines** - when processing massive amount of data (e.g. classification, NLP, data extraction,
+  etc.), every bit of speed improving can accelerate the processing time of the whole corpus.
+  Using Streaming, you can respond faster even for partial responses.
+  and continue with the pipeline
+- **Use functions/agents with streaming** - this library makes functions and agents with Streaming easy peasy.
