 - A Python API (`asr_client` package)
 - A CLI tool (`asr-client` entry point → `asr_client.__main__:main`)

 ```bash
-./setup.sh    # Sync git submodules
+./setup.sh    # Install pre-commit hooks
 ./install.sh  # Create .venv + install package with test extras
 ```
 
-- `setup.sh` — submodule sync/init only (`git submodule sync/update --init --recursive`).
+- `setup.sh` — clones the `techmo-pl/pre-commit` tooling from GitHub and installs hooks.
 - `install.sh` — creates `.venv` via `uv`, runs `uv pip install -e ".[test]"`. Accepts an optional `VENV_PATH` argument (default: `.venv`). Checks upfront for `uv`, `gcc`, Python headers, and PortAudio headers — fails with a clear message if any are missing.

 ## gRPC / Protobuf Rules
 
-- Generated protobuf files (`*_pb2.py`, `*_pb2_grpc.py`) come from `submodules/asr-api-python` and are produced at install time — never commit them.
-- All gRPC stubs are imported via `from asr_api import v1, v1p1, dictation`. The `asr_api` package is installed from the submodule under the name `techmo-asr-api` (see `[tool.uv.sources]` in `pyproject.toml`), not from PyPI.
-- If `asr_api` imports fail after cloning, run `./setup.sh` then `./install.sh`.
-- `tox.ini` installs the submodule directly as a dep: `deps = -e {toxinidir}/submodules/asr-api-python`.
