+## Implementation note
+
+This Space runs **inference from `app.py`** (vocabulary, phonemization, ONNX sessions). It does **not** install the upstream [`blue`](https://github.com/maxmelichov/BlueTTS) Python package from GitHub (that package name replaced the old `lightblue-onnx` wheel and would conflict with pip’s expected name in a flat `requirements.txt`).
+
 ## Model weights
 
 ONNX checkpoints are **not** stored in this Space repo (file-size limits). On first startup, `download_models.py` fetches them from the public model repo **[notmax123/blue-onnx](https://huggingface.co/notmax123/blue-onnx)** into `./onnx_models/`.
