The guidelines Titus has followed thus far:

- easy to install and use for non-Python programmers;

- testing-focused: features should not be added if they interfere with ease-of-use for testing; in particular, features to support programmatic Web browsing should not make testing more difficult.

- keep the docs up to date;

- write tests for bugs before fixing the bugs;

- keep high (80-90%) test coverage of code
