 > Escape RegExp special characters
 
-
 ## Install
 
 ```
-$ npm install --save escape-string-regexp
+$ npm install escape-string-regexp
 ```
 
-
 ## Usage
 
 ```js
 const escapeStringRegexp = require('escape-string-regexp');
 
-const escapedString = escapeStringRegexp('how much $ for a unicorn?');
-//=> 'how much \$ for a unicorn\?'
+const escapedString = escapeStringRegexp('How much $ for a 🦄?');
+//=> 'How much \\$ for a 🦄\\?'
 
 new RegExp(escapedString);
 ```
 
+You can also use this to escape a string that is inserted into the middle of a regex, for example, into a character class.
