@@ -91,3 +95,9 @@ This rule is largely inspired by the MarkdownLint rule
 It is not clear how this rule, which is disabled by default, differs from

 to work with nested list blocks and block quotes.
+
+## Fix Description
+
+The containers will be altered so that they start at the beginning of "the line".
+As that definition was not clearly understood [Rule MD007](./rule_md007.md) was
+created to more clearly handle the issue.
