 performance-faster-string-find
 ==============================
 
-Optimize calls to ``std::string::find()`` and friends when the needle passed is
-a single character string literal. The character literal overload is more
-efficient.
-
-Examples:
-
-.. code-block:: c++
-
-  str.find("A");
-
-  // becomes
-
-  str.find('A');
-
-Options
--------
-
-.. option:: StringLikeClasses
-
-   Semicolon-separated list of names of string-like classes. By default only
-   ``::std::basic_string`` and ``::std::basic_string_view`` are considered.
-   Within these classes, the check will only consider member functions named
-   ``find``, ``rfind``, ``find_first_of``, ``find_first_not_of``,
-   ``find_last_of``, ``find_last_not_of``, ``starts_with``, ``ends_with``,
-   ``contains``, or ``operator+=``.
+The `performance-faster-string-find check` is an alias, please see
