+# Development
+
+## Editable install
+
+We recommend installing into an isolated environment — the dependencies include several GB of CUDA-built wheels.
+
+```bash
+python -m venv .venv && source .venv/bin/activate
+```
+
+For development, install the package in editable mode so changes to the source
+tree are picked up without reinstalling:
+
+```bash
+pip install -e .
+```
+
+or with [`uv`](https://docs.astral.sh/uv/):
+
+```bash
+uv venv && source .venv/bin/activate
+```
+
+```bash
+uv pip install -e .
+```
+
+## Pre-commit hooks
+
+This repo uses [pre-commit](https://pre-commit.com/) to run lint, format, and
+type checks (`ruff`, `mypy`, etc.) before each commit.
+
+Install once per clone:
+
+```bash
+pip install pre-commit
+pre-commit install
+```
+
+`pre-commit install` registers a git hook in `.git/hooks/pre-commit`, so it
+requires the directory to be a git repo. The hooks now run automatically on
+`git commit` against staged files.
+
+To run the hooks manually against every file in the repo (useful right after
+the first install, or in CI):
+
+```bash
+pre-commit run --all-files
+```
+
+The first run downloads each hook's environment (ruff, mypy, etc.) into
+`~/.cache/pre-commit/` and may take a minute. Subsequent runs are fast.
+
+To bump pinned hook versions in `.pre-commit-config.yaml`:
+
+```bash
+pre-commit autoupdate
+```
