-> [!WARNING]
-> The documentation of this feature is a work in progress.
+Not all paginations are [length-aware](#-length-aware-paginations), some may be built in a way where each page has a cursor pointing to the next page.
+
+We can tackle this kind of pagination by indicating the key or the header holding the cursor:
+
+```php
+LazyJsonPages::from($source)->cursor('pagination.cursor');
+```
+
+The cursor may be a number, a string or a URI: Lazy JSON Pages supports them all.
