+### Jmes Path (JmesPathMatcher)
+The JMESPath language is described in an ABNF grammar with a complete specification.
+A JSON body will be considered to match a path expression if the expression returns either a non-null single value (string, integer etc.), or a non-empty object or array.
+
+#### C#
+```csharp
+var server = WireMockServer.Start();
+server
+  .Given(
+    Request.Create().WithPath("/jmespath_example").UsingGet()
+      .WithBody(new JmesPathMatcher("things.name == 'RequiredThing"));
+  )
+  .RespondWith(Response.Create().WithBody("Hello"));
+```

 An XML document will be considered to match if any elements are returned by the XPath evaluation.
