+var TestSchema = @"
+  input MessageInput {
+    content: String
+    author: String
+  }
+
+  type Message {

+    content: String
+    author: String

+
+  type Mutation {
+    createMessage(input: MessageInput): Message
+    updateMessage(id: ID!, input: MessageInput): Message
+  }
+
+  type Query {
+   greeting:String
+   students:[Student]
+   studentById(id:ID!):Student
+  }
+
+  type Student {
+   id:ID!
+   firstName:String
+   lastName:String
+   fullName:String 
+  }";
+
+var server = WireMockServer.Start();
+server
+    .Given(Request.Create()
+        .WithPath("/graphql")
+        .UsingPost()
+        .WithGraphQLSchema(TestSchema)
+    )

+
+## CSharp Code (CSharpCodeMatcher)
+*Advanced!* With this matcher you can use complex C# code to match an JObject or string value.
+* You need to include the NuGet package [WireMock.Net.Matchers.CSharpCode](https://www.nuget.org/packages/WireMock.Net.Matchers.CSharpCode/)
+* Note that this functionality will only work if enabled in the settings (`AllowCSharpCodeMatcher = true`).
+* The argument-name from the string or JObject to match will be `it`.
+
+#### C# option
+```csharp
+var server = WireMockServer.Start();
+server
+    .Given(Request.Create().WithPath("/cs")
+        .WithParam("from", new CSharpCodeMatcher("return it == \"x\";")))
+    .RespondWith(Response.Create()
+        .WithBody("cs match")
+    );
+```
