+## Static Methods
+
+If you have to write a script to automatically set slugs across a collection, you can use the `getUniqueSlug` static method this package exposes on models.
+
+For example, if you want to programmatically set all blog posts to have slugs, run this script (note that you should run the updates serially as the example shows to prevent slug conflicts):
+
+```js
+const Promise = require('bluebird'); // exposes `Promise.each`
+
+const BlogPost = require('../app/models/blog-post.js');
+
+(async () => {
+  const blogPosts = await BlogPost.find({}).lean()exec();
+  await Promise.each(blogPosts, async blogPost => {
+    blogPost.slug = null;
+    blogPost.slug = await BlogPost.getUniqueSlug(blogPost.title);
+    return blogPost.save();
+  }));
+})();
+```
