 ## Usage
 
+### Basics
+
 Wildcard-match comes built in ESM, CommonJS and UMD formats and includes TypeScript typings. The examples use ESM imports, which can be replaced with the following line for CommonJS: `const wcmatch = require('wildcard-match')`.
 
 The default export is a function of two arguments, first of which can be either a single glob string or an array of such patterns. The second argument is optional and can be either an [options](#options) object or a separator (which will be the value of the `separator` option). Wildcard-match compiles them into a regular expression and returns a function (usually called `isMatch` in the examples) that tests strings against the pattern. The pattern, options and the compiled RegExp object are available as properties on the returned function:
 
 ```js
 import wcmatch from 'wildcard-match'
 
-const isMatch = wcmatch('src/?ar', '@')
+const isMatch = wcmatch('src/?ar')
 
 isMatch('src/bar') //=> true
 isMatch('src/car') //=> true
 isMatch('src/cvar') //=> false
 
 isMatch.pattern //=> 'src/?ar'
-isMatch.options //=> { separator: '@' }
-isMatch.regexp //=> /^src\/+?[^/]ar\/*?$/
+isMatch.options //=> {}
+isMatch.regexp //=> /^src[/\\]+?[^/\\]ar[/\\]*?$/
 ```
 
 The returned function can be invoked immediately if there is no need to match a pattern more than once:
