+# Code Style
+
+We follow the [Google Python Style
+Guide](https://google.github.io/styleguide/pyguide.html) with a few
+modifications to match the *Google internal* version.  The primary one is the
+use of 2 space indents.
+
+Use [yapf](https://github.com/google/yapf) to keep the code formatted nicely.
+You can set up an auto-save hook in your editor, or run it manually:
+
+```shell
+# one time setup:
+pip install yapf
+
+# format files:
+yapf -i *.py
+```
