 ## Versions supported
 
-- Jetpack supports PHP 5.6, as per WordPress' own requirements. Keep that in mind when developing for Jetpack.
+- Jetpack supports PHP 7.0, as per WordPress' own requirements. Keep that in mind when developing for Jetpack.
 - Jetpack follows [WordPress Core's standards](https://make.wordpress.org/core/handbook/best-practices/coding-standards/), with a few additions. The best way to ensure that you adhere to those standards is to set up your IDE [as per the recommendations here](./development-environment.md#use-php-codesniffer-and-eslint-to-make-sure-your-code-respects-coding-standards).
 - Jetpack supports the WP current version and the immediate previous version. So if WP version is 4.6, Jetpack will support it, as well as 4.5. It's desirable that when Jetpack is installed in older versions, it doesn't fail in a severe way.
 - We support the latest two versions of all major browsers, except IE, where we currently only support 11 and Edge. (see [Browse Happy](http://browsehappy.com) for current latest versions).

+This ruleset is intended to be used with PHPCompatibiity's `testVersion` set to `7.0-`.
 If used with [automattic/jetpack-phpcs-filter](https://github.com/Automattic/jetpack/blob/trunk/projects/packages/phpcs-filter/)'s per-directory configuration,
 you may run into a situation where a subdir wants to be compatible down to a later version, but as PHPCompatibiity uses `<config>` for `testVersion` the setting cannot be directly altered per directory.
 
 To assist with this case, we provide additional rulesets that disable PHPCompatibility rules detecting issues that only apply to older versions:
 
-* `<rule ref="Jetpack-Compat-70" />` will disable rules detecting issues that only apply to PHP < 7.0.
 * `<rule ref="Jetpack-Compat-71" />` will disable rules detecting issues that only apply to PHP < 7.1.
 * `<rule ref="Jetpack-Compat-72" />` will disable rules detecting issues that only apply to PHP < 7.2.

+Note this isn't a perfect replacement for raising `testVersion`, as it cannot _add_ PHPCompatibility rules that do not trigger when `testVersion` indicates support for PHP 7.0.
 For example, `Jetpack-Compat-74` disables the `PHPCompatibility.Classes.NewTypedProperties.Found` rule ("Typed properties are not supported in PHP 7.3 or earlier") but cannot enable more specific rules like `PHPCompatibility.Classes.NewTypedProperties.UnionTypeFound` ("Union types are not present in PHP version 7.4 or earlier") that would be triggered if `testVersion` were set to `7.4-`.
 
 You may also run into cases where certain subdirectories contain code that is not intended to run under WordPress. We provide additional rulesets to help with this situation as well:
