-`Slugger` is exposed from marked as `marked.Slugger`:
-
-```js
-import { marked } from 'marked'
-const slugger = new marked.Slugger()
-```
-
-`slugger` has the `slug` method to create a unique id from value:
-
-```js
-slugger.slug('foo')   // foo
-slugger.slug('foo')   // foo-1
-slugger.slug('foo')   // foo-2
-slugger.slug('foo 1') // foo-1-1
-slugger.slug('foo-1') // foo-1-2
-...
-```
-
-`slugger.slug` can also be called with the `dryrun` option for stateless operation:
-```js
-slugger.slug('foo')                    // foo
-slugger.slug('foo')                    // foo-1
-slugger.slug('foo')                    // foo-2
-slugger.slug('foo', { dryrun: true })  // foo-3
-slugger.slug('foo', { dryrun: true })  // foo-3
-slugger.slug('foo')                    // foo-3
-slugger.slug('foo')                    // foo-4
-...

 `flags` has the following properties:
