-KC3 maps are like Elixir maps, they are key-values enclosed in `%{}` :
+KC3 tuples are arrays of `Tag`.

+## 1.22.1 Examples
 
 ```elixir
-ikc3> a = %{id: 1, title: "My title", message: "Hello, world !"}
-%{id: 1,
-  title: "My title",
-  message: "Hello, world !"}
+ikc3> a = {:ok, "My title", "Hello, world !"}
+{:ok, "My title", "Hello, world !"}
 ```

-To update an existing map you can use Map.put like this :
-
-```elixir
-ikc3> a = %{id: 1, title: "My title"}
-%{id: 1,

-ikc3> a = Map.put(a, :message, "Hello, world !")
