+# Development
+
+If you haven't already, set up a virtual environment in the top-level of the project:
+
+```
+# Create the virtual environment
+python3 -m venv venv
+# Activate the virtual environment
+source venv/bin/activate
+# Install the project's dependencies
+pip install -r requirements.txt
+```
+
+The dependencies installed for development include those described in `setup.py` as well as `pytest`, which is used to run the automated test suite.
+
+To run `pytest`, first export your account `EMAIL` and `PASSWORD`, and also a hex-encoded `GSFID`, as environment variables. Next, run `pytest`.
+
+```
+export EMAIL='XXX'
+export PASSWORD='XXX'
+export GSFID='XXX'
+python -m pytest -v
+```
