+## Usage
+
+```javascript
+var replaceBeforeLast = require( '@stdlib/string/base/replace-before-last' );
+```
+
+#### replaceBeforeLast( str, search, replacement, fromIndex )
+
+Replaces the substring before the last occurrence of a specified search string.
+
+```javascript
+var str = 'beep boop';
+var out = replaceBeforeLast( str, ' ', 'loop', str.length );
+// returns 'loop boop'
+
+out = replaceBeforeLast( str, 'o', 'bar', str.length );
+// returns 'barop'
+```
+
+The search starts at the end of the string and proceeds backwards to the beginning. To start the search at a specified index, specify an integer for the `fromIndex` argument.
+
+```javascript
+var str = 'beep boop beep';
+var out = replaceBeforeLast( str, ' ', 'loop', 5 );
+// returns 'loop boop beep'
+```

+
+## Notes
+
+-   If a search string is not present in a provided string, the function returns the provided string unchanged.
+-   If a search string is an empty string, the function returns the provided string unchanged.
+-   If `fromIndex` is less than `0`, the function returns the provided string unchanged.
