-- in the developer guide.
--
-- __For the latest version of AWS WAF__, use the AWS WAFV2 API and see the
-- <https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html AWS WAF Developer Guide>.
-- With the latest version, AWS WAF has a single set of endpoints for
-- regional and global use.
--
-- Inserts or deletes ActivatedRule objects in a @RuleGroup@.
--
-- You can only insert @REGULAR@ rules into a rule group.
--
-- You can have a maximum of ten rules per rule group.
--
-- To create and configure a @RuleGroup@, perform the following steps:
--
-- 1.  Create and update the @Rules@ that you want to include in the
--     @RuleGroup@. See CreateRule.
--
-- 2.  Use @GetChangeToken@ to get the change token that you provide in the
--     @ChangeToken@ parameter of an UpdateRuleGroup request.
--
-- 3.  Submit an @UpdateRuleGroup@ request to add @Rules@ to the
--     @RuleGroup@.
--
-- 4.  Create and update a @WebACL@ that contains the @RuleGroup@. See
--     CreateWebACL.
--
-- If you want to replace one @Rule@ with another, you delete the existing
-- one and add the new one.
--
-- For more information about how to use the AWS WAF API to allow or block
-- HTTP requests, see the
-- <https://docs.aws.amazon.com/waf/latest/developerguide/ AWS WAF Developer Guide>.
