+### Grouping code blocks
+
+The [SuperFences][5] extension which is part of the [PyMdown Extensions][6]
+package adds support for grouping code blocks with tabs. This is especially
+useful for documenting projects with multiple language bindings.
+
+Example:
+
+````
+``` bash tab="Bash"
+#!/bin/bash
+
+echo "Hello world!"
+```
+
+``` c tab="C"
+#include <stdio.h>
+
+int main(void) {
+  printf("Hello world!\n");
+}
+```
+
+``` c++ tab="C++"
+#include <iostream>
+
+int main() {
+  std::cout << "Hello world!" << std::endl;
+  return 0;
+}
+```
+
+``` c# tab="C#"
+using System;
+
+class Program {
+  static void Main(string[] args) {
+    Console.WriteLine("Hello world!");
+  }
+}
