 Thanks for your interest in contributing to the HTTPS Everywhere `rulesets`! There's just a few things you should know before jumping in. First some terminology, which will help you understand how exactly `rulesets` are structured and what each one contains:
 
 * `ruleset`: a scope in which `rules`, `targets`, and `tests` are contained. `rulesets` are usually named after the entity which controls the group of `targets` contained in it.  There is one `ruleset` per XML file within the `src/chrome/content/rules` directory.
