+
+===============
+Find a Document
+===============
+
+You can retrieve a single document from a collection by calling the ``where()`` and
+``first()`` methods on an Eloquent model or a query builder.
+
+Pass a query filter to the ``where()`` method and then call the ``first()`` method to
+return one document in the collection that matches the filter. If multiple documents match
+the query filter, ``first()`` returns the first matching document according to the documents'
+:term:`natural order` in the database or according to the sort order that you can specify
+by using the ``orderBy()`` method.
+
+Example
+-------
+
+This usage example performs the following actions:
+
+- Uses the ``Movie`` Eloquent model to represent the ``movies`` collection in the
+  ``sample_mflix`` database.
+- Retrieves a document from the ``movies`` collection that matches a query filter.
+
+The example calls the following methods on the ``Movie`` model:
+
+- ``where()``: matches documents in which the value of the ``directors`` field includes ``'Rob Reiner'``.
+- ``orderBy()``: sorts matched documents by their ascending ``_id`` values.
+- ``first()``: retrieves only the first matching document.
