-**Likable is a powerful, real-time AI coding assistant that allows you to develop and preview Gradio applications through a conversational interface.**
+**Build Gradio apps, using only a chat interface.**
 
-Just describe the application you want to build, and watch as the AI agent writes the code, handles dependencies, and spins up a live, interactive preview for you in real-time. It's the fastest way to go from idea to a working Gradio app.
+We've built the app we wish we had at the start of the [Gradio Agents & MCP Hackathon 2025](https://huggingface.co/Agents-MCP-Hackathon); a Gradio app to build Gradio apps, almost like our favorite Swedish AI startup.

+## ⚠️ IMPORTANT
+**Please note:** This public demo space is shared among all users - everyone sees the same app and shares the same API key. For this reason, we've disabled the settings tab and are using a free version of DeepSeek V3 from OpenRouter.
+
+**For private use or if you encounter rate limits**, we recommend duplicating this space to your own account and configuring it with your personal API keys, by either using Space sectres or uncommenting line 742-784 and 806-817 in `src/app.py` to enable the settings tab.

 ## 🛠️ How It Works
 
-Likable uses a `smolagents` based AI agent specifically prompted for Gradio development. The workflow is as follows:
+Likable leverages `smolagents` for its AI agent. The workflow is as follows:
 
 1.  **User Prompt**: You provide a task in the chat interface (e.g., "Create a simple calculator app").
 2.  **Agent Execution**: The agent receives the prompt and uses its available tools (`create_new_file`, `python_editor`, `install_package`, `test_app_py`) to accomplish the task. All generated code is created inside a secure `sandbox` directory.
