+Try out your first program by writing:
+
+  print("Hello world");
+
+Create your first variable by writing:
+
+  var myString: str = "Hello world!";
+  print(myString);
+
+Perform your first calculations by writing:
+
+  var result: num = 3.14 * 9;
+  print(result as str);
+
+Like other languages, Kipper provides loops like while-loops:
+
+  var i: num = 0;
+  while (i < 5) {
+    print(i as str);
+    i = i + 1;
+  }
+
+And you can also use for-loops:
+
+  for (var i: num = 0; i < 5; i = i + 1) {
+    print(i as str);
+  }
+
+You can also use conditionals:
+
+  var x: num = 10;
+  if (x > 5) {
+    print("x is greater than 5");
+  } else {
+    print("x is less than or equal to 5");
+  }
+
+You can also define functions:
+
+  func add(a: num, b: num): num {
+    return a + b;
+  }
+  print(add(3, 4) as str);
+`
+    .split("\n");
