 The [`data-computed`](/reference/attribute_plugins#data-computed) attribute creates a new signal that is computed based on an expression. The computed signal is read-only, and its value is automatically updated when any signals in the expression are updated.
 
 ```html
-<div data-signals-input="''" data-computed-repeated="$input.repeat(2)">
-  <input data-bind-input />
-  <div data-text="$repeated">

+    <div data-text="$repeated">
+        Will be replaced with the contents of the repeated signal
+    </div>
+</div>>
 ```
 
 This results in the `$repeated` signal's value always being equal to the value of the `$input` signal repeated twice. Computed signals are useful for memoizing expressions containing other signals.
