| * `Base Domain HSTS Preloaded` - A domain's base domain is HSTS preloaded. This is subtly different from `HSTS Entire Domain`, which inpects headers on the base domain to see if HSTS is set correctly to encompass the entire zone. This checks the preload list directly. | ||
| * `HSTS Preload Pending` - A domain is "preload pending" when it appears in the [Chrome preload pending list](https://hstspreload.org/api/v2/pending) with the `include_subdomains` flag equal to `true`. The intent of `pshtt` is to make sure that the user is _fully_ protected, so it only counts domains as HSTS preloaded if they are _fully_ HSTS preloaded (meaning that all subdomains are included as well). | ||

@jsf9k -- Would it be worth explicitly spelling out what is meant by "base domain" here? e.g. foo.gov but not www.foo.gov nor other.foo.gov ?

The term "base domain" is defined earlier in the README, at line 101. Do you think that definition needs to be repeated here?
