+## Project Overview
+
+LeRobot is a PyTorch-based library for real-world robotics, providing datasets, pretrained policies, and tools for training, evaluation, data collection, and robot control. It integrates with Hugging Face Hub for model/dataset sharing.
+
+## Tech Stack
+
+Python 3.12+ · PyTorch · Hugging Face (datasets, Hub, accelerate) · draccus (config/CLI) · Gymnasium (envs) · uv (package management)
+
+## Development Setup
+
+```bash
+uv sync --locked                            # Base dependencies
+uv sync --locked --extra test --extra dev   # Test + dev tools
+uv sync --locked --extra all                # Everything
+git lfs install && git lfs pull             # Test artifacts
+```
+
+## Key Commands
+
+```bash
+uv run pytest tests -svv --maxfail=10                 # All tests
+DEVICE=cuda make test-end-to-end                      # All E2E tests
+pre-commit run --all-files                           # Lint + format (ruff, typos, bandit, etc.)
+```
+
+## Architecture (`src/lerobot/`)
+
+- **`scripts/`** — CLI entry points (`lerobot-train`, `lerobot-eval`, `lerobot-record`, etc.), mapped in `pyproject.toml [project.scripts]`.
+- **`configs/`** — Dataclass configs parsed by draccus. `train.py` has `TrainPipelineConfig` (top-level). `policies.py` has `PreTrainedConfig` base. Polymorphism via `draccus.ChoiceRegistry` with `@register_subclass("name")` decorators.
+- **`policies/`** — Each policy in its own subdir. All inherit `PreTrainedPolicy` (`nn.Module` + `HubMixin`) from `pretrained.py`. Factory with lazy imports in `factory.py`.
+- **`processor/`** — Data transformation pipeline. `ProcessorStep` base with registry. `DataProcessorPipeline` / `PolicyProcessorPipeline` chain steps.
+- **`datasets/`** — `LeRobotDataset` (episode-aware sampling + video decoding) and `LeRobotDatasetMetadata`.
+- **`envs/`** — `EnvConfig` base in `configs.py`, factory in `factory.py`. Each env subclass defines `gym_kwargs` and `create_envs()`.
+- **`robots/`, `motors/`, `cameras/`, `teleoperators/`** — Hardware abstraction layers.
+- **`types.py`** and **`configs/types.py`** — Core type aliases and feature type definitions.
+
+## Repository Structure (outside `src/`)
+
+- **`tests/`** — Pytest suite organized by module. Fixtures in `tests/fixtures/`, mocks in `tests/mocks/`. Hardware tests use skip decorators from `tests/utils.py`. E2E tests via `Makefile` write to `tests/outputs/`.
+- **`.github/workflows/`** — CI: `quality.yml` (pre-commit), `fast_tests.yml` (base deps, every PR), `full_tests.yml` (all extras + E2E + GPU, post-approval), `latest_deps_tests.yml` (daily lockfile upgrade), `security.yml` (TruffleHog), `release.yml` (PyPI publish on tags).
+- **`docs/source/`** — HF documentation (`.mdx` files). Per-policy READMEs, hardware guides, tutorials. Built separately via `docs-requirements.txt` and CI workflows.
+- **`examples/`** — End-user tutorials and scripts organized by use case (dataset creation, training, hardware setup).
+- **`docker/`** — Dockerfiles for user (`Dockerfile.user`) and CI (`Dockerfile.internal`).
+- **`benchmarks/`** — Performance benchmarking scripts.
+- **Root files**: `pyproject.toml` (single source of truth for deps, build, tool config), `Makefile` (E2E test targets), `uv.lock`, `CONTRIBUTING.md` & `README.md` (general information).
+
+## Notes
+
+- **Mypy is gradual**: strict only for `lerobot.envs`, `lerobot.configs`, `lerobot.optim`, `lerobot.model`, `lerobot.cameras`, `lerobot.motors`, `lerobot.transport`. Add type annotations when modifying these modules.
+- **Optional dependencies**: many policies, envs, and robots are behind extras (e.g., `lerobot[aloha]`). New imports for optional packages must be guarded or lazy. See `pyproject.toml [project.optional-dependencies]`.
+- **Video decoding**: datasets can store observations as video files. `LeRobotDataset` handles frame extraction, but tests need ffmpeg installed.
+- **Prioritize use of `uv run`** to execute Python commands (not raw `python` or `pip`).
