+Updating the requirements
+-------------------------
+
+The requirement files are pinned and controlled by pip-tools compile. To update
+the pins, run nox on a Linux system with all supported versions of Python included.
+For example, using a docker image:
+
+    $ docker run --rm -v $PWD:/nox -t thekevjames/nox nox -f /nox/noxfile.py -s compile tools
