+### Hash Fields in Snapshots
+
+If some fields of our snapshot are too big, for example a binary field with a lot of data, then we can use the HashField option.
+The HashField option creates a Hash of the field value and therefore each time only the hash is compared. 
+If there is a change in the field value, then the snapshot match will fail.
+
+```csharp
+[Fact]
+public void ImageSnapshot_HashImageBinary()
+{
+    // arrange
+    var serviceClient = new ServiceClient();
+
+    // act
+    TestImage image = serviceClient.CreateMonaLisaImage();
+
+    // assert
+    Snapshot.Match(image, matchOptions => matchOptions.HashField("Data"));
+}
+```
+Example Snapshot with Hash
+```json
+{
+  "Id": 3450987,
+  "OwnerId": "0680faef-6e89-4d52-bad8-291053c66696",
+  "Name": "Mona Lisa",
+  "CreationDate": "2020-11-10T21:23:09.036+01:00",
+  "Price": 951868484.345,
+  "Data": "m+sQR9KG9WpgYoQiRASPkt9FLJOLsjK86UuiXKVRzas="  
+}
+```
+
+The field(s) to hash can be located via JsonPath or via field name.
+
+Hash Field Examples:
+
+```csharp
+// Hash the field 'Data' of the child node 'Thumbnail' of the person
+Snapshot.Match<Person>(person, matchOptions => matchOptions.HashField("Thumbnail.Data"));
+
+// Hash the field 'Data' of the first thumbnail in the 'Thumbnails' array of the image
+Snapshot.Match<Person>(person, matchOptions => matchOptions.HashField("Thumbnails[0].Data"));
+
+// Ignores the field 'Data' of all 'Thumbnails' nodes of the image
+Snapshot.Match<Person>(person, matchOptions => matchOptions.HashField("Thumbnails[*].Data"));
+
+// Ignores all fields with name 'Data'
+Snapshot.Match<Person>(person, matchOptions => matchOptions.HashField("**.Data"));
+```
+
+### Assert Fields in Snapshots
 
 Sometimes there are fields in a snapshot, which you want to assert separately against another value.
