+For forum admins, migration is a one-line change — swap the package, keep your settings and stored SEO data:
+```sh
+composer remove pipecraft/flarum-ext-id-slug
+composer require xxb/id-slug
+php flarum cache:clear
+```
+
+### Updating
+```sh
+composer update xxb/id-slug
+```
+
+### How to Use
+1. Install extension
+2. Enable **ID Slug** extension
+3. Basics > Slug Driver(Discussion) > Select **id** slug driver
+
+### Notice
+
+- If you are using the sitemap(fof/sitemap) extension, you need to upgrade to v1.0.1 or above. （[Use Slug Driver system properly](https://github.com/FriendsOfFlarum/sitemap/issues/30)）
