-
-:::note[Experimental Feature]
-The Llama Stack Playground is currently experimental and subject to change. We welcome feedback and contributions to help improve it.
-:::
-
-The Llama Stack Playground is a simple interface that aims to:
-- **Showcase capabilities and concepts** of Llama Stack in an interactive environment
-- **Demo end-to-end application code** to help users get started building their own applications
-- **Provide a UI** to help users inspect and understand Llama Stack API providers and resources
-
-## Key Features
-
-### Interactive Playground Pages
-

-# (Experimental) LLama Stack UI
-
-## Docker Setup
-
-:warning: This is a work in progress.
-
-## Developer Setup
-
-1. Start up Llama Stack API server. More details [here](https://llamastack.github.io/latest/getting_started/index.htmll).
-
-```
-llama stack list-deps together | xargs -L1 uv pip install
-
-llama stack run together
-```
-
-2. (Optional) Register datasets and eval tasks as resources. If you want to run pre-configured evaluation flows (e.g. Evaluations (Generation + Scoring) Page).
-
-```bash
-llama-stack-client datasets register \
---dataset-id "mmlu" \
---provider-id "huggingface" \
---url "https://huggingface.co/datasets/llamastack/evals" \
---metadata '{"path": "llamastack/evals", "name": "evals__mmlu__details", "split": "train"}' \
---schema '{"input_query": {"type": "string"}, "expected_answer": {"type": "string", "chat_completion_input": {"type": "string"}}}'
-```
-
-```bash
-llama-stack-client benchmarks register \
---eval-task-id meta-reference-mmlu \
---provider-id meta-reference \
---dataset-id mmlu \
---scoring-functions basic::regex_parser_multiple_choice_answer
-```
-
-3. Start Streamlit UI
-
-```bash
-uv run --with ".[ui]" streamlit run llama_stack.core/ui/app.py
-```
-
