+## Setting up for local development
+
+This package requires Python >= 3.5.
+
+As a Python package, you can set up a development environment by cloning this repo and running:
+
+    python3 -m pip install -e .
+
+from the repo directory.
+
+You can also install the tools we use for testing and development with:
+
+    python3 -m pip install -r dev-requirements.txt
+
+
+### Auto-format with black
+
+We are trying out the [black](https://github.com/ambv/black) auto-formatting
+tool on this repo.
+
+You can run `black` manually on the repo with:
+
+    black .
+
+in the root of the repo. You can also enable this automatically on each commit
+by installing a pre-commit hook:
+
+    ./git-hooks/install
+
+After doing this, every time you make a commit,
+the `black` autoformatter will run,
+ensuring consistent style without you having to worry too much about style.
+
+## Running the tests
+
+After doing a development install, you can run the tests with:
+
+    pytest -v
+
+in the repo directory.
