-This is an official plugin for the [`regex`](https://github.com/slevithan/regex) library that adds support for recursive matching up to a specified max depth *N*, where *N* must be between 2 and 100.

Generated regexes are native `RegExp` instances, and support all JavaScript regular expression features except numbered backreferences (support could be added in future versions).
 
 Recursive matching is added to a regex via one of the following:
 
 - `(?R=N)` — Recursively match the entire regex at this position.
-- `\g<name&R=N>`, `\g<N&R=N>` — Recursively match the contents of the group referenced by name or number at this position.
-  - The `\g` subroutine must be called *within* the referenced group.
+- `\g<name&R=N>` or `\g<number&R=N>` — Recursively match the contents of the group referenced by name or number at this position.
+  - The `\g` subroutine must be *within* the referenced group.
 
-Recursive matching supports named captures and named backreferences, which are independent per depth level. So e.g. `groups.name` on a match object is the value captured by group `name` at the top level of the recursion stack.
+The recursion depth limit is provided where *`N`* is shown above.

 This matches sequences of non-parens in one step with the nested `+` quantifier, and avoids backtracking into these sequences by wrapping it with an atomic group `(?>…)`. Given that what the nested quantifier `+` matches overlaps with what the outer group can match with its `*` quantifier, the atomic group is important here. It avoids exponential backtracking when matching long strings with unbalanced parens.
